¶Release Notes

¶Version 1.3.0

¶Core

• Implemented a new solver for fat simulation.
• Implemented a new constraint to preserve the internal shape of fat tissue.
• Implemented a new constraint to preserve the volume of fat tissue.
• Extended all existing solvers to support stiffness overrides per constraint type.

¶Maya

• Added AdnFat deformer.
• Added stiffness overrides per constraint type to all deformers.
• Implemented dynamic loading of AdonisFX shelf and removed the MAYA_SHELF_PATH configuration from the module file.
• Improved UX to prevent informative dialogs to prompt.
• Improved UX to prevent dialogs to prompt when running commands from script.

¶Bug Fixes

• Fixed a bug that was redistributing the masses per point in very specific cases and only if the painted masses map was not the default one.
• Fixed a bug that was causing the velocities damping not work when point masses were too large.

¶Known Limitations

• Interaction muscle-to-muscle is not supported. AdonisFX-1211
• Exporter and Importer do not support locators and sensors. AdonisFX-1215

¶Version 1.2.0

¶Core

• Added support for multiple targets in AdnSkin solver.
• Extended the uber constraints initialisation to build constraints with the closest point on the closest target.
• Allow all the solvers to use the internal triangulation of the geometry to build the constraints.
• Extended the distance, fiber and shape preservation constraints initialisation to build constraints based on the triangulated mesh.
• Added support in AdnSkin solver to simulate even if no targets are provided.

¶Maya

• Added Targets array plug to AdnSkin deformer to connect multiple targets.
• Added Triangulate Mesh option to all AdonisFX deformers to enable or disable the use of the triangulated version of the mesh for building the constraints.
• Added two new buttons to the shelf and two new entries in the menu to add and remove targets from an AdnSkin deformer.
• Added support for debugging distance and fiber constraints.

¶Known Limitations

• Slide on geometry constraints in Fast mode are limited to simple setups. They need to run in Quality mode to ensure stability in complex scenarios. AdonisFX-1213
• Volume ratio gain effect is dependent to the total volume of the muscle. This might require to use volume ratios with a range different to the default [0, 2] if needed. AdonisFX-1137
• Interaction muscle-to-muscle is not supported. AdonisFX-1211
• Exporter and Importer do not support locators and sensors. AdonisFX-1215
• Fat simulation is limited to the current features in AdnSkin solver. AdonisFX-879

¶Version 1.1.2

¶Bug Fixes

• Fixed a bug in the Slide Collision Constraints that was overcorrecting in case of intersection with the collider with a magnitude greater than the collision threshold. AdonisFX-1258

¶Version 1.1.1

¶Bug Fixes

• Fixed a bug in how the gravity was evaluated. Now the value from the UI represented in m/s² is converted to cm/s². AdonisFX-1250

¶Considerations for backward compatibility

• Due to the fix introduced in this version, in order to have the scenes created with previous versions work the same way, it is needed to set the gravity value in all AdonisFX nodes divided by 100. For example, if the AdonisFX setup in v1.1.0 (or older) used a gravity of 980, now this attribute needs to be changed to 9.8. If the setup did not use gravity, no adjustment needs to be done.

¶Version 1.1.0

• Attachment to geometry constraints in AdnMuscle and AdnRibbonMuscle solvers. Multiple target geometries are supported.
• Slide on geometry constraints in AdnMuscle and AdnRibbonMuscle solvers. Multiple target geometries are supported.

• Debugger system improved to be dependent to the visibility of the simulated geometry.
• Added a sanity check to Max Sliding Distance attribute to warn the user if the input value is too high for the given target mesh.

• Plain AdnLocator with a custom shape for visualisation purposes.
• AdnEdgeEvaluator: A node to compute the compression map of a deformed geometry.
• AdnWeightsDisplayNode: A node to visualise the paintable maps while painting from the AdonisFX Paint Tool.

• Learn Muscle Patches Tool: An intuitive UI to configure and run the AdnLearnMusclePatches command.
• Sensors Connection Editor: A simple UI to make connections easily from sensors and locators to AdonisFX deformers.
• AdonisFX Paint Tool: Custom tool to manipulate the paintable maps of the AdonisFX deformers to ensure that the solvers receive valid distribution of weights.
• A debugger system compound by an AdnData node and an AdnDebugLocator to visualise information internal to the solvers such as connections to attachments, fiber directions, etc.

¶Known Limitations

• The Max Sliding Distance parameter in AdnSkin and AdnSimshape is represented in scene units. The higher this value is, the more units in the space the sliding constraint allows a vertex to slide on. If the polygons of the target geometry to slide on are very little compared to that value, then the sliding constraint will be time and memory consuming. AdonisFX-997
• The activations debugger in AdnSimshape is limited to the Parallel and Serial evaluation modes. AdonisFX-1026
• The debugger system draws debug data independently to the visibility of the mesh. AdonisFX-802
• Enabling and disabling fibers display from the AdonisFX menu does not restore the previous status of the debug settings of the affected deformers. AdonisFX-998
• The AdonisFX Paint Tool does not refresh the painted maps if the attachments or the slide on segment constraints are removed while the tool is opened. Restarting the tool is needed. AdonisFX-999
• The AdnLocatorRotation does not draw the angle shape if the three inputs (start, mid and end positions) are aligned, i.e. when the angle is 180 degrees. AdonisFX-1000
• The Importer tool creates and configures the deformers assuming that all the required inputs exist in the scene. If any of those is not found (e.g. target mesh in AdnSkin), they have to be reassigned to an existing object manually. AdonisFX-1001
