Controls now have mouse proximity visibility option, meaning they are only visible when mouse cursor is in close proximity to them
Remove unused PyMel imports
Improved debug logging on startup, added output of file structure of BroTools folder to be able to quicker spot missing or corrupt files when reviewing logs
Updated FBX SDK libraries
BroTools Core \ Network Installer was missing some required files, preventing it from launching
Fix decode errors in configuration.py
Fixed configuration.py import error (missing icon_generator)
Fixed BroAI not working in Maya 2026
This is a huge release, as it marks yet another milestone in BroDynamics development. It could've been considered a BroDynamics 3.0 release, but the version bump from 2024 to 2025 also looks like a good one.
The main feature of this release is a new simulation engine, which is a completely new and custom simulation engine written entirely from scratch. This means that all calculations are now handled by BroDynaimics directly, instead of relying on Maya's built-in physics engines like Nucleus or Bullet. With this new engine I now have full control over the simulation process, and I can implement new features and improvements much faster and more efficiently, and in a way that could be, at least in theory, transferred to other software.
But what does it mean for the user? Here's a breakdown:
All of this is available with this release.
All of the old simulation modes are still available, but they are now considered "Legacy" modes.
For advanced users realtime physics is also already available through the use of new BroDynamics Maya Nodes, and more user-friendly UIs are on my roadmap for future releases.
However the functionality of the new engine exposed to the UI and even nodes right now is just the tip of the iceberg, and I am working on bringing even more features and power to it in the future.
This update may require you to restart Maya after updating, simple BroTools - Reload might not work.
New simulation engine - custom physics engine written from scratch.
New Chain simulation mode based on new engine
New Point simulation mode based on new engine
Realtime physics simulation setups (in alpha)
Fixed batch simulation Get button functionality
Various internal improvements
Fixed Presets saving and loading, updated to work with new modes and added curve support
Added Hind Leg IK rig (actually it's a combo of IK, Hind Leg IK, Hind Leg with Toe, depending on number of selected joints)
Improved renaming process that better avoid name clashing during renaming
Transparent background disabled for all Maya versions, due to instability of current solution. AnimHUD is now just a dockable window that can be docked near a timeline. I'm going to revise the transparency feature in future releases.
Added new tool! Foot Planter. A few clicks to fix feet going under the ground, sliding and so on, helpful when cleaning up mocap.
Added an option to configure Floating License server address from License Manager UI
Improved filtering, fixing a bug that would not properly apply Exlusion filter on first run
Various internal and install procedure improvements
This release adds a new tool called BroAI, which is a new AI powered tool for Maya. It brings the power of Large Languge Models to assist you with your workflows - it can create new scripts, perform actions and answer questions.
You can read more about it in documentation here - https://docs.brotools.tech/BroAI/intro.html
Key feature that sets BroAI apart from alternatives is that it supports OpenAI ChatGPT and Anthropic Claude, but also any OpenAI API compatible service, which includes local models and many other providers.
You can use free and open source local models, you can use free models on OpenRouter or you can opt for the State of the Art best models from OpenAI or Anthropic. The choice is yours.
Improve hardware fingerprinting on Windows to fix wmic related errors.
Added new tool!
Added a new environment variable BROTOOLS_FLOATING_DONT_LEASE_ON_START which, if set to 1, will prevent BroTools requesting a lease from the TurboFloat server on startup.
Added LicensingAPI with functions to request and drop licenses from the TurboFloat server with Python.
Attribute Spring and Noise modes now check if an attribute is keyable and ignore it if it's not, instead of throwing an error. Which means you can now select a whole bunch of objects for simulation and hit simulate without worrying if there are locked attributes there or not.
gif_playblast_size_px setting for GIF Playblast now takes a string with 2 space separated numbers width height
Improved locale encoding detection which should fix some problems with BroTools not starting or not working properly on Windows systems with some specific locales, for example German.
Manually Dropping and Requesting lease from TurboFloat server was not working properly, it has been fixed
Hotfix for 2024.06.17
Fix cannot import name 'prod' from 'math' error preventing BroTools from starting in Maya 2022.
This release has been a long time coming, and brings some improvements that are well overdue! I'll preface this by saying that for the past year or so I had to sort out a lot of boring legal and financial issues that were stalling BroTools development quite a lot. I'm happy to announce that most of those boring issues were now sorted, and I should finally be able to get back to the fun parts - actual development. And I started with revamping big parts of the development, build, release processes with a goal of eliminating as much friction as possible in adding support for new Maya versions across all platforms. This change should also allow me to focus more on improving all the tools.
Unfortunately I had to finally drop support for Python 2. Keeping it supported is something that is takign significant development time and effort, and complicates many things. The industry is moving away from it, and Python 2 has been officially an unsupported language since January 1, 2020, 4.5 years ago. You will still be able to download older verisons of BroTools and use them if you need to run them on Maya 2019-2020.
There was also a regression with some functionality in Maya 2025. AnimHUD relied on some Qt hacks to get it into the viewport which stopped working in Maya 2025 and Qt6. So for now it will revert to using a regular floating non transparent window (in Maya 2025 only) until I can figure out what to do with it next. I'm considering either using a more integrated method of viewport rendering for AnimHUD, or changing it into a simple dockable window which will fit right under or over the timpeline, like most other animation tools do.
When upgrading to this release please note that it has some significant changes which may be buggy. If anything happens - revert to an older version using a backup (there's a restore_backup.mel script which you can drag and drop into viewport, and also available from BroTools menu) or by downloading an archive.
Added "Cleanup All Static Curves" command to the menu which runs delete -all -staticChannels; command
Support for Maya 2025 added on all platforms
Support for 2024 on MacOS and Linux restored
Improved build and release processes to reduce amount of work needed for adding new Maya versions support and testing
Added "Sort Outliner Objects" to BroTools - Common Tools menu. A simple script to reorder objects by alphabet in outliner. Available for free with the core (network installer).
Python Custom Scripts are now executed with global() namespace, which should allow using functions and more
Python Custom Scripts are now wrapped in open\close undo chunk, so should fall under a single undo operation. Potentially breaking, if you already used undoinfo within your custom scripts, you may need to remove those commands
Maya 2019-2020 (Python 2) support is dropped, if you need to use BroTools or BroDynamics with these versions - download version 2023.07.06.
A hotfix for 2023.12.30 release
Fix missing .json configuration files for Noise and Attribute Spring simulation modes.
It's been a while since we had new simulation modes in BroDynamics, and I am excited to report that there are 2 new simulation modes added in this release - Noise and Attribute Spring!
New simulation mode - Noise! Uses configurable Perlin Noise to drive any numeric attribute(s) in Maya. Preserves original animation.
New simulation mode - Attribute Spring! Adds springiness to any animated numeric attribute(s) in Maya. Follows original animation.
Chain Simple Tension attribute was not working unless collisions were involved. This has been fixed, and Tension attribute should now always affect the animation.
Added a Close button for AnimHUD
Potentially Breaking on Windows The way BroTools finds user directory on Windows is changed to be more reliable and support having Documents folder in non-standard locations. For some users configuration settings might reset to default, as new config files will be created in a different location. By default BroTools writes config files in it's own directory, so it may primarily affect some studio installations.
Unicode support when reading and writing config files and in preferences menus
Fix License Manager window causing a crash on Maya 2024.2
Fix - trying to use collisions with nHair simulation was causing unsupported operand type(s) for +: 'NucleusNode' and 'str' error, this was fixed
Support for Maya 2024 on Windows
Installer script improvement - Changed the way Maya Modules directory is found, it now relies on environment variable which should be more reliable.
Installer script improvement - Added an option to manually specify Maya modules directory where BroTools.mod file is installed, to address cases when it does not detect the correct one.
Installer script improvement - Installer script now supports installing BroTools on a different drive from Maya modules directory
Adjusted a "New version" message text to include a reminder that Lifetime licenses are only limited to receiving updates within 1 year after purchase.
Many of BroTools menu entries will now show help annotations, and more will be coming with each release.
Disabled "AnimationOnly" option on FBX exporter globablly after finding out that it has a high likelihood of breaking poses in exported animations. At least until I can find a proper solution to this problem.
Server side - updater will now properly work with lifetime licenses which expired - it will properly limit maximum version (previously it was causing issues and breaking installations)
Hotfix release! Fixes "Object has no transform" error.
Fixed "Object has no transform" error that was introduced in 2023.02.07 release and affected Maya 2022+ installs (Python 3 specific).
Nothing particularly huge in this release, but a lot of useful improvements and bug fixes across the board.
Point (nParticle), Chain (nParticle) and Chain (nHair) simulation modes now properly support simulation in negative frames. This feature was broken for some time.
Auto Playblast and GIF Playblast will now run ffmpeg commans in parallel to greatly speed up mp4 and gif encoding when using multiple cameras
Auto Playblast and GIF Playblast will no longer show CMD windows when using ffmpeg, unless Debug Level is set to 0 in Preferences
Auto Playblast and GIF Playblast now use Maya's built-in progress bar
Fixed a bug where switcher dropdown menu checkboxes would reset on any object selection change and after running Bake
Fixed a bug where Bake Existing checkbox would have no effect
Renamed BroSelector to Finder to better reflect what it does
Changed it's logic on how it works without selection. With no objects selected it will now operate on all objects in the scene, allowing you to quickly search objects by name.
Core BroNode class instantiation was optimized globablly to prevent re-instantiation of already instantiated class. What this means is that it should significantly improve performance in some areas of BroTools, but it may introduce new unexpected bugs that fell through the cracks during testing.
Multiple other minor core bug fixes and improvements
Adjusted how path to the BroTools folder is found internally, to fix an issue with launching BroTools from a network mountpoint on Linux
Improved internet and license server connectivity detection to be more reliable
Fixed an edge case causing some errors to fail to show properly in Script Editor
Added support for Maya 2023 (Which means Maya 2023 is now supported on Windows and Linux. MacOS was not yet tested)
Fixed startup crashing when using Floating Licensing on Linux with Maya 2022
Made hostname reading code more resilient to non-ascii encoding, fixing errors like Generic HTTP Exception: 'utf8' codec can't decode byte 0xc0 in position 0: invalid start byte;
Changed text of the message shown when license key verification date expired to avoid confusion.
Fixed some Python 3 errors that were breaking some online functionality
Improvements across most tools, and Maya 2023 support on Windows!
activeModules in BroDynamics settings (and brodynamics.cfg) is now replaced with disabledModules. By default all modules are now active, and those listed in disabledModules will not be loaded. If you changed this setting before - make sure to adjust it. If you did not change it - this change will not influence you.
New Animation Layer checkbox now properly works with Batch Simulation
Chain (nParticle) mode that was introduced in 2021.6.30 could be missing from your installation if you updated from earlier versions, it was only available on new installations, due to updater not updating the config file properly. This issue has been addressed by changing config logic - replacing activeModules with disabledModules
AnimHUD performance optimization - reduced background redraw rate from 40 fps to 12 fps.
Now supports renaming of most Maya objects. In case it can't rename something it will print a warning in ScriptEditor, and rename everything it can
Better support for selecting objects with same name for renaming (in different parts of the hierarchy)
Maya 2023 support on Windows (Linux and MacOS were not yet tested on Maya 2023)
TurboFloat libraries for Linux and MacOS were missing from distribution, leading to Failed to get the floating license lease: Unhandled exception. /BroTools/core/system/libTurboFloat.so: cannot open shared object file: No such file or directory // # error, this problem was fixed
Some systems were getting # RuntimeError: The system does not seem to have a valid MAC and # BroToolsError: name 'O____o____o____0__o__0__o____0_O_O__O__o___0__O__O' is not defined [NameError, 'utilities.on_plugin_initialized'] licensing errors, a potential fix to this issue was added in this release
Fix ping: bad linger time. error on Linux
The biggest change in this release is the introduction of AnimHUD - a new UI for Animation Toolbox! It places tweeener, IKFK Switcher and other most useful tools right at the top of your viewport.
Greet AnimHUD! This is a HUD interface for primary animation tools. It integrates with the main Maya viewport to provide non-distracting buttons for commonly used Animation Toolbox tools like: tweener, ikfkswitcher, euler filter and others. Refer to documentation for more info.
Main IKFKSwitcher window was changed, and now it only contains primary buttons. All extra options were moved to the right-click menu. This was done to make it more compact and compatible with HUDA.
Icons were refactored to be more intuitive, recognizable and have better contrast. Icons now primarily use 2 colors.
Added icons for more tools and actions
Fixed a bug preventing BroTools 2021.12.14 from starting with fresh installs
Main tweeener window was changed, and now it only contains the slider. All extra options were moved to the right-click menu. This was done to make it more compact and compatible with HUDA.
Focus of this release is on improving Chain (nParticle) mode, rewriting the way it calculates twisting and overall improving the way it works. Which means less flipping for most rigs :) This release also brings a long anticipated feature - overwriting latest animation layer. Which means that you won't have to wait for the simulation to 'Undo' anymore! This release also has UX improvements to the licensing system and restoring backups.
Added new global Overwrite Previous Layer checkbox. This should greatly improve iteration speed, you can use this instead of Ctrl+Z when iterating. If you run simulation with New Animation Layer checkbox on, it will remember last created layer (until you close the window). If you check Overwrite Previous Layer checkbox and run the simulation again, it will remove previous layer, create a new one with the same name and run simulation again. Layers can be renamed, it won't affect BroDynamics's link to the layer.
Chain (nParticle) - much improved twisting calculations, they now use a better and more reliable method
Chain (nParticle) - improved stability and reliability
Added Reinstall Here option to license manager, which helps simplify the process of moving your license between PCs. With this option you can now jump onto a new PC, go to License Manager and select "Reinstall Here", and in one action it will move your license to your current PC. It is exactly the same as performing Uninstall and then Install manually.
Added "Copy Project Path" and "Copy Scene Path" menu actions to File Tools - these will copy paths to current project and scene to the clipboard respectively
Added Restore Backup menu option to BroTools menu to launch restore_backup.mel script from UI
Fixed a name "system_locale" is not defined startup bug that showed up on MacOS and Linux
More bug fixes for Chain (SpringMagic) rewrite. Sorry about frequent releases, but they are required to tackle problems promptly.
BroDynamics will now perform some sanity checks before running simulations and display a warning window for common problems like incorrect number of selected objects, or selecting objects without transforms, etc.
Chain (SpringMagic): Added extra logging for Problem with the API object returned by __apiobject__ method; No object matches name: None error suspects, hopefully next occurence will have better logs to determine the issue
BroDynamics now better keeps track of timeline playback speed and properly restores it even in most error events.
Fix chain modes not starting simulation due to parenting errors
Chain (SpringMagic): Fixed Invalid arguments for flag 'worldUpVector'. Expected ( float, float, float ), got MVector error
Chain (SpringMagic): Fix Problem with the API object returned by __apiobject__ method; No object matches name: None error
Another bugfix release for Chain (SpringMagic) rewrite
Chain (SpringMagic): Fixed gitter bug with Flex parameter above 0
Chain (SpringMagic): Fixed simulation twisting incorrectly with some rigs
Chain (SpringMagic): Fixed MEulerRotation error introduced in 2021.11.23
Bugfix release for Chain (SpringMagic) rewrite and further improvements to supporting different locales. Also restore_backup.mel script is back, and should allow you to revert to any of the previous versions that you had installed.
Fixed Expected (distance, distance, distance) got MVector error in Chain (SpringMagic)
Fixed invalid null reference in method 'MVector___eq__' error in Chain (SpringMagic) that was happening on collision with capsule
Fixed bug when using Flex parameter in Chain (SpringMagic)
Improved support for non-english locales on Windows for running shell commands, improved detecting of current terminal encoding
restore_backup.mel script was not included with distribution archives, a bug in the release script that was fixed
Most interesting change of this release is a long overdue rewrite of Chain (SpringMagic) module that offers performance increase of around 8-10% and better Undo support. It also improves support of non-english Windows locales.
Chain (SpringMagic) mode was rewritten from pymel to cmds and OpenMaya to remove dependency on PyMEL and improve performance by around 8-10%
Chain (SpringMagic) mode now better supports undo for operations like Adding Capsules and Wind
restore_backup.mel script has been added to BroTools folder. Drag and Drop it into Maya window to restore to a backup of previously installed version.
Improved handling of SSL connection with the server to help identify SSL issues
Improved support for non-English locales on Windows
Improved logging
Fix shell command errors on Brazilian Portuguese locale in Windows
Improved error handling for Floating License system
Fixed a bug causing changing TurboFloat server port to raise TurboFloatInetError
Hotfix release triggered by necessity to address a critical bug in the floating licensing system. But it also brings a long awaited feature for BroDynamics Batch simulation mode!
New Animation Layer, Do Not Refresh Viewport and Disable Viewport checkboxes now also work with Batch Simulation
Fixed critical bug in floating licensing system. TurboFloatFailError was causing BroTools to exit with error, when in reality it's normal part of TurboFloat library operation and should've been ignored.
Added an option to bake only existing poses, instead of baking every frame. This allows to transfer animation between IK and FK in a much cleaner and editable way
Bake and Transfer now respect keyframe range selection on the timeline (Shift+Click+Drag region marked in red)
Fixed IKFK Switcher crashing on Maya 2022 with Python 3
Fixed IKFK Switcher compatibility issues on Maya 2022 with Python 3
Tools that rely on matching existing keyframes (like Transfer motion) will now respect timeline range selection
Overall speed optimization (BroNode initialization speed up)
Fixed a bug causing downloads of some non-essential files to fail on Maya 2020 and earlier, resulting in "Download finished with errors" message
Hotfix release aimed at adding a workaround for licensing server connectivity issues caused by Let's Encrypt's root certificate issues.
Added an option to disable SSL verification on the client side
Fixed a bug preventing an error window from showing on license key renewal failure
Hotfix release that fixes critical bugs in the licensing system in Maya 2022 with Python 3. Also added an option to run euler filter in IKFK Switcher.
Added an option to run euler filter after switching
Further improvements to licensing and update systems stability in Maya 2022 with Python 3 and overall
Attempting to run updater without license key will now show proper error
In Maya 2022 with Python 3 there was a bug preventing BroTools from properly working if Windows system language was set to anything other than English. This was fixed.
Tweeener added icon
A small release that improves Gravity workflow in Chain (nHair) mode with Collisions enabled and tweaks licensing system to more reliably detect server connection.
Fixed Gravity not working in Chain (nHair) mode with Collision mode checkbox enabled. This was a design flaw, users were meant to use Gravity force instead, but it caused more confusion. Now if Gravity is not 0 it will create a force.
Tweaked internal server connection test to be more reliable and reduce false negatives causing Offline Activation window to appear when there is an acitve internet connection available
A small release with some important hotfixes for Renamer and Auto Euler option added to Tweeener
Fix trim processor not trimming words from the end
Fix a bug causing File - Open to not work on Maya 2022
Loading presets from a file was additive which is not an expected behavior. Now existing processors are replaced with loaded preset.
Auto Euler filter option - it will run Euler filter before and after tweening to help with gimbal lock issues
Added Substeps and Timescale controls to all nucleus based simulation modes - Chain (nHair), Spring (nParticle), Chain (nParticle)
Improved "Welcome back" window for those who upgrade from BroDynamics 2.x
New processor - Split. Allows splitting strings into multiple words by specific separator. Is similar to using Replace and replacing with space.
Trim processor can now work on words instead of characters. In combination with Split or CamelCaseSplit it can allow to easily remove parts of names of unequal length
This release is not as large as the previous one, but it has some useful improvements and important bug fixes. This release is most recommended for MacOS users as it fixes the incorrect HardwareID detection in licensing system and for people writing scripts and automating their simulation workflows with Python, as logging and Python API documentation were improved.
Clicking simulate button in RBD mode will now show a notification saying that Simulate button is not used in RBD mode, to reduce confusion. RBD has a slightly different workflow revolving around using buttons available in Workbench of RBD mode UI.
Improved documenation on Python API
Improved simulator logging, simulation properties logging was moved to INFO level and now contains proper args and kwargs for using the simulator.run function:
```
// BroTools | INFO || chain.run:82 | Run Simulator for module: Chain (nHair).
Args: ([u'nurbsCircle1', u'nurbsCircle2', u'nurbsCircle3'],)
Kwargs: {'preserveAnimation': True, 'collisionMode': False, 'forces': [], 'shiftDistance': 1.0, 'dontRefresh': False, 'followBaseTwist': True, 'preserveInertia': True, 'preAlign': False, 'autoShiftDistance': True, 'cycleIterations': 0, 'aimRotation': True, 'multiPassSimulation': False, 'simulationProperties': {'attractionScale[1].attractionScale_Position': 1, u'startCurveAttract': 0.01, u'stiffnessScale[1].stiffnessScale_FloatValue': 1.0, 'stiffnessScale[0].stiffnessScale_Position': 0, u'damp': 0.0, u'compressionResistance': 10.0, u'gravity': 0.0, u'attractionScale[0].attractionScale_FloatValue': 1.0, u'drag': 0.05, u'attractionScale[1].attractionScale_FloatValue': 1.0, u'stiffnessScale[0].stiffnessScale_FloatValue': 1.0, 'attractionScale[0].attractionScale_Position': 0, u'bendResistance': 1.0, u'stretchResistance': 10.0, 'stiffnessScale[1].stiffnessScale_Position': 1, u'attractionDamp': 0.15, u'collideWidthOffset': 0.0, u'mass': 1.0}, 'skipControls': 1, 'eulerFilter': True, 'matchPositions': False, 'colliders': [], 'deleteNucleus': True}
//
```
Chain (nParticle) mode was ignoring timeline selection range. This has been fixed, now it will properly simulate only within selected timeline range (Shift+Click+Drag on timeline)
Fixed a bug causing forces from Collisions and Forces window were ignored in Chain (nHair) mode
Improved internal error handling
Fixed an issue where BroTools was unable to get proper Hardware ID on MacOS and showing error in License Manager
Version 2021.6.30 introduced a bug that causes a lot of errors that should halt execution and show error instead pass silently. This has been fixed, some errors will now properly raise exception windows, others will leave warnings in the log.
This release is a rather big one and has a lot of focus on improving BroDynamics, fleshing out existing features and adding new simulation mode to BroDynamics as well as two completely new tools - Renamer! You can read more about it below.
For those people who prefer to own their software and not pay for a subscription I also have good news - Lifetime purchase option is coming back in this release in a form of lifetime version which is limited to 1 year of updates. It will cost more, but I've decided to give a fair discount to everyone who already bought BroDynamics 2.x in the past.
Another very important part of this update is of most interest to studios, thanks to LimeLM BroTools now has support for Floating licenses. Floating licenses also come in a form of subscription or lifetime.
I decided to rename simulation modes to make their naming more transparent and intuitive to what they do. Documentation was updated to reflect this change as well, however there may still be traces of the old naming here and there. If you notice any, please, report so I can fix it.
Another big addition to the family of BroTools is a new Renamer tool. It's modular and is inspired by tools like Advanced Renamer for Windows. The best way to describe it is to check out some screenshots and a video which you can find in Documentation here
I'm also further improving BroTools UX around updating and licensing. For example in previous updates I've introduced pre-update backup, allowing users to restore to previous version in case there is an issue with an update. But you had to manually find and extract a zip archive which may've not been very convenient. So now I've added a restore_backup.mel script which you can drag and drop into Maya's viewport and it will do it for you. It has to be a separate script, because of an assumption that if an update failed then BroTools might not even be able to load a menu.
There was also a critical bug concerning MacOS and Linux users that was making BroTools to not properly detect hardware IDs, and this change may require re-installing your licenses. Sadly it's not possible to auto-correct it in this case like it happened before.
New Chain (nParticle) mode! Combines the best of... well, seems like all previous modes. It has proper inertia for both overlap and overshoot motion like Chain mode, but it's easier to work with and more predictable like Simple Chain. And it supports looping animation in a similar way as Point mode, meaning proper transfer of both position and inertia in the seam area. And it follows your existing animation and poses! And collisions with objects (any nCloth - Passive Collider). It will likely become new primary simulation mode for most animators.
Updated default values in Chain mode to provide a more uniform result
Renamed simulation modes in UI for transparency:
New tool - Renamer! Ultimate modular renaming tool for Maya, stack string processing actions in any order, preview rename, save and load presets and more!
Floating Licenses, powered by LimeLM TurboFloat server
Lifetime licenses
Added 'restore_backup.mel' script. If there is any issue with the update you can drag and drop this script into Maya's viewport much like install.mel, and it will let you select a backup to restore to.
Updater windows now include warnings asking user to close all Maya instances before updating, as it may cause issues with the update. Additionally on Windows update check will not run if more than 1 Maya instance is running.
Added an option to skip an update, that will remember your choice and no longer notify you about an update to this specific version. If there's another version released that's newer than the one you skipped - it will notify you again.
Improved stability of licensing server connection test
Reduced spacing of some UI elements, specifically in License Manager and Preference Windows, to make UIs more compact
UI Style update
Added more tools icons for menu
Server side support for updating to and downloading specific versions, part of the work required to implement lifetime licenses
Improved stability of BroTools - Debug - Reload BroTools command
Improved licensing system to better handle multiple tools installs on same machine
Fix critical bug causing BroTools to not properly get hardware ID on MacOS and Linux
Highlight of this release is addition of Cycle\Seamless Looping for Point and Chain modes!
Chain mode - also tweaked how it simulates start and end frame. It was skipping first 2 frames of the simulation to preserve initial pose, this was a rudimentary feature that was taking it's roots way back from version 1.x. Now it will simulate and match all frames including first ones, required for
Simple Chain mode - Is Loop? option renamed to Create seamless loop, should be more intuitive to understan what it does
Custom Scripts menu now supports running mel scripts
Custom Scripts menu now has reload button which will allow adding new scripts without restarting Maya or reloading entire BroTools plugin. It's only required if you add new files to custom scripts folder, reloading is not required to detect changes in scripts' code, they are loaded from disk for every execution
Custom Scripts now have Python and Mel icons
BroDynamics on startup will check Undo Queue state, if it's off it will suggest to enable it
Point mode - previously simulation was ending 1-2 frames before the final frame. Now it simulates until the very last frame properly. Tweaked frame walking logic to better match frames on different steps.
Fixed some logging bugs introduced by python 2 to 3 convertion
Fixed 'Object's name 'bro_dynamics_windowWorkspaceControl' is not unique.' error when trying to reopen BroDynamics UI or other BroTools dockable UIs when it's been docked before closing Maya
New Tool! Tweeener - allows creating in-between and overshoot poses with a slider. Well, if you know TweenMachine - you know what Tweeener is. But it now comes included with AnimationToolbox, has sleeker UI and is going to be upgraded over time with new features.
Fixed bug with SquashStretch tool showing errors and not reverting slider on selection change
Improved message for offline activaiton
IKFK Switcher window is now dockable
You can now dock some windows together, for example you can combine IKFK Switcher, Tweeener and BroDynamics into one window. This concept will be improved in future versions
All dockable windows will now remember their docked state between maya sessions and when closed and reopened
Added an option to revert to old version to the main BroTools menu for users coming from BroDynamics 2.x
Fixed some HTTP error messages not showing up
New Animation Layer checkbox! It will automatically generate a new animation layer and all simulated keyframes will go there. Should allow to improve iteration speed a lot, no need to remove keyframes or wait for undo command to finish, just disable current simulaion layer and run simulation again. It also preserves your existing keyframes, allows to compare different simulation results or stack simulations on top of each other.
GIF Playblast and other playblast tools that expected camera names to have "Cam_" will now support namespaces
Menus for fileops advertised in 2021.5.14 were missing on some platforms, this has been fixed
License Manager window will now automatically select "Install" if you only have 1 license, so you can just click "Next"
License Manager will now show a warning suggesting to start a trial and a "Go Back" button if you don't have any licenses
Start Trial button was not available after running License Manager once
Pre-update backups will now include date and time when they were created
Fixed License Manager window width, it would open up too narrow to show license action dropdowns, causing confusion
Improvements to better support those upgrading from BroDynamics 2.x
Fixed config read error preventing Point tab from showing in Maya 2022+ with Python 3
Added File Tools menu containing some tools to help working with files and file browser. Available to both BroDynamics and BroTools users
Locate current scene - will reveal current scene folder in your system's file browser (Explorer in Windows)
Locate current project - will reveal current project folder in file browser
Find Textures - for every file texture in the project it will scan current project directory and subdirectories for a file with matching name and replace the path to the file. Can help find missing textures in the scene.
Find Textures In - does the same thing as Find Textures, but allows user to specify directory to scan in. Also recursive. Can be used to find missing textures or to replace existing textures with other textures in another folder, as long as they have same filenames.
A backup of BroTools folder will now be created before every update to allow user to easily roll back in case of a failed update
Licensing improvements
Fixed Python 3 (Maya 2022+) bug causing updater to fail file downloads
Changes how BroTools identifies hardware IDs, should help make it more stable and unify between different Python versions. It will attempt to upgrade old HID in the database, but if it fails it may require you to reactivate your license. To do it open License Manager, enter your email, click "Next" select "Uninstall" next to your license, click Next. Close any windows that show up, reopen License Manager, enter your credentials, click Next - select Install from the dropdown. Click Next. Your license should be bound to new ID.
