BroTools Changelog

improvement

• 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.

new

• Brand new simulation mode - Noise! Uses configurable Perlin Noise to drive any numeric attribute(s) in Maya.

fix

• TODO broSpring_wind node breaks Chain (SpringMagic) simulation

fix

• Fix - trying to use collisions with nHair simulation was causing unsupported operand type(s) for +: 'NucleusNode' and 'str' error, this was fixed

new

• Support for Maya 2024 on Windows

improvement

• 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.

fix

• 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)

fix

• Fixed "Object has no transform" error that was introduced in 2023.02.07 release and affected Maya 2022+ installs (Python 3 specific).

improvement

• 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

fix

• 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

fix

• Point (nParticle), Chain (nParticle) and Chain (nHair) simulation modes now properly support simulation in negative frames. This feature was broken for some time.

improvement

• 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

fix

• 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

improvement

• Added support for Maya 2023 (Which means Maya 2023 is now supported on Windows and Linux. MacOS was not yet tested)

fix

• 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

new

• Maya 2023 support on Windows (Linux and MacOS were not yet tested on Maya 2023)

fix

• 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

improvement

• 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.

fix

• 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

improvement

• AnimHUD performance optimization - reduced background redraw rate from 40 fps to 12 fps.

improvement

• 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

fix

• Fixed a bug preventing BroTools 2021.12.14 from starting with fresh installs

new

• 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.

new

• 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.

new

• 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

improvement

• Added Restore Backup menu option to BroTools menu to launch restore_backup.mel script from UI

fix

• Fixed a name "system_locale" is not defined startup bug that showed up on MacOS and Linux

new

• 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.

improvement

• Chain (nParticle) - much improved twisting calculations, they now use a better and more reliable method

• Chain (nParticle) - improved stability and reliability

fix

improvement

• Improved error handling for Floating License system

fix

• Fixed a bug causing changing TurboFloat server port to raise TurboFloatInetError

fix

• 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.

improvement

• Tools that rely on matching existing keyframes (like Transfer motion) will now respect timeline range selection

• Overall speed optimization (BroNode initialization speed up)

new

• 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

improvement

• Bake and Transfer now respect keyframe range selection on the timeline (Shift+Click+Drag region marked in red)

fix

• Fixed IKFK Switcher crashing on Maya 2022 with Python 3

• Fixed IKFK Switcher compatibility issues on Maya 2022 with Python 3

improvement

• Attempting to run updater without license key will now show proper error

fix

• 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

new

• Added an option to run euler filter after switching

improvement

• 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

fix

• 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.

fix

• 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.

improvement

• 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

• New processor - Split. Allows splitting strings into multiple words by specific separator. Is similar to using Replace and replacing with space.

improvement

improvement

• Improved internal error handling

fix

• 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.

improvement

• 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}

  //

  ```

fix

• 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

new

• 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.

improvement

• 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 licensing system to better handle multiple tools installs on same machine

fix

• Fix critical bug causing BroTools to not properly get hardware ID on MacOS and Linux

new

• 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.

improvement

• Updated default values in Chain mode to provide a more uniform result

• Renamed simulation modes in UI for transparency:

  • Point - Spring (nParticle)
  • Simple Chain - Chain (Spring Magic) (Because it's based on approach used in Spring Magic script for 3ds Max)
  • Chain - Chain (nHair)
  • RBD - RBD (Bullet)

  

new

• New tool - BroRenamer! Ultimate modular renaming tool for Maya, stack string processing actions in any order, preview rename, save and load presets and more!

new

• Highlight of this release is addition of Cycle\Seamless Looping for Point and Chain modes!

improvement

• 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

fix

• 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

improvement

• 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

fix

• Fixed some HTTP error messages not showing up

new

• 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.

fix

• Fixed bug with SquashStretch tool showing errors and not reverting slider on selection change

fix

• Menus for fileops advertised in 2021.5.14 were missing on some platforms, this has been fixed

new

• 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.

improvement

• GIF Playblast and other playblast tools that expected camera names to have "Cam_" will now support namespaces

improvement

• 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

fix

• Start Trial button was not available after running License Manager once

improvement

• 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

new

• 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.

improvement

• 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

fix

• Fixed config read error preventing Point tab from showing in Maya 2022+ with Python 3

fix

• Fixed Python 3 (Maya 2022+) bug causing updater to fail file downloads

improvement

• 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.

improvement

• Add file download progress indication to downloader

fix

• Fixed a severe bug affecting Unix (Mac and Linux) users that was breaking some of the menu entries from showing up, for tools like IKFK Switcher, broSelector and some others

new

• Added licensing system to allow for more flexible licensing terms, subscriptions and trial periods

• Updater reworked from scratch featuring per-file sync with checksum checks

• New calendar based versioning system, instead of arbitrary numbers, it's now YEAR.MONTH.DAY of release. Versioning is now unified among all tools, as they all share same core modules.

improvement

• Code improvements and optimizations

• Installation script was improved to not require Maya restart

• Cleaned up and improved logging styling, removed timestamps from logs as there is no use for them

• New error message window

• Transform matching now respects locked attributes

• trackTransform now respects locked attributes

• Better config option names in all configuration windows

• BroNode updates and improvements

• Maya 2019-2020 improved compatibility

• Added prefix to internal menu names to avoid potential clashing with other plugins

• Added a configuration option to fallback to using a more reliable QTextBrowser instead of QWebEngineView. There was a slowly but surely growing number of users reporting Maya hanging when trying to import it, and disabling anti-malware software was not always a solution.

• core.cfg was deprecated, as it was only used to define config and log directories, which was moved to environment variables

• Maya menu improvements and bug fixes
