Additive Layers (Alpha version)

An example of using Additive Layers. Each layer stores its own animation data, and when they are enabled simultaneously,
this data is added together, forming a complete animation.

This new tool allows you to separate an object’s motion into several ‘layers’ that are combined together when the animation is played.

To access this feature, select Animation Layers from the Window menu:

Easing

An example of using tangents to change the distribution of the frames on Intervals.

This new feature allows to adjust the spacing of the motion, making the animation faster or slower in a concrete interval.

To use this feature, enable it by clicking the Easing button on the Timeline

This will add Easing controls to the Intervals on the Timeline.
Using these controls, you can adjust the ‘weight’ of the keyframe, altering the spacing of the interpolated trajectory, as shown in the example above.

To hide Easing controls, simply click the same button again.
And if you’d like to reset the Easing weights on the selected keyframes, click the Reset easing weights to default button:

AutoPosing Updates 

Hands and feet now correctly adjust to the environment.

Improved AutoPosing for Quadrupeds.

Localizations

Cascadeur UI now supports multiple languages. Languages can be set in the top right corner of the window:

Interface Updates

You can now create your own UI elements using PySide.

Root Motion is now Motion Generation.

You can now set the transparency for the Isometric Grid using the Grid lines alpha and Grid background alpha values (found in Settings Window → Visualizers).

New Camera settings:

Found on the Scene Settings panel, the new Camera exposure group contains parameters for controlling ISO, shutter speed and aperture values that can come in handy in creating good-looking renders.

Environment light intensity (Scene Settings → Environment tab) is now controlled with a slider along with the numerical value (that was already there).

Commands menu has been separated into two menus: Commands (contains core scripts) and Scripts (contains additional scripts)

You can now set colors for the Trajectory before and after the current frame.
For this, use the Trajectory Color Before Current Frame and Trajectory Color After Current Frame settings found in the Trajectory Tool category of the Settings Window.

Added a modifier for controlling the visibility of the floor surface.

Added an option to invert camera zoom.

Other Updates

Go to t-pose now works with Point Controllers and Joints (previously, it only worked with Box Controllers).

Added an option to import animation from BVH files. 
Available in the Commands menu through the Import BVH animation item (only works for animation, other content of BVH files is not currently supported; to import whole scenes, use different file formats).

Added support for a simple MCP server.
Available in the Scripts menu through the MCP section.

Rigging Tools has been optimized for better performance.

Collision Penetration Cleaning now takes Fulcrums into account.
Also, this tool is now included by default in the AutoPhysics pass (only with ground and Kinematic colliders).

Inbetweening and Motion Generation (formerly known as Root Motion) have been trained on larger datasets, resulting in better output.
Also, Inbetweening now passes styles between keys.

Added Python Stub files - allows intellisense in Python API modules.

Textures have been deprecated. Use Materials instead.

Now you can use several Materials on a single mesh.
If an imported object has several Materials, they are all recognized correctly (previously, only one Material per mesh was supported).

Sample characters now come with default Materials.

Updated LiveLink for Unreal Engine 5.8.
Also, LiveLink now correctly creates animation when the resource path contains UTF characters.

Updated the neural network meshes used for AutoPosing and Retargeting.

Changed the visualization logic for Rig Unit elements so that it no longer draws lines to parent elements that are not transforms.

Fixes

Added a check for missing names of dynamic behaviors in the Fix Scene command.

Added visualization of multiple materials and textures from assets in Filament.

Fixed a false error appearing when no 3D mouse was connected.

Fixed viewport artifacts in Filament under heavy load.

Fixed a Jolt crash caused by float overflow.

Fixed the description of the Roblox export script.

Added support for reading material properties such as metallic and roughness from a specific RGB channel.

Renamed the Add to New Layer button.

Fixed linked scenes displaying hidden objects.

Finger autoposing controller squares are now hidden when Autoposing: Fingers visibility is disabled.

Fixed the center-of-mass local axis not being visible in Autoposing view mode.

Fixed shifts in UI widgets when opening scenes.

Pressing Enter in the input field when creating a track now creates the track.

Changed the Secondary Motion floor collision behavior.

Simplified the AutoPosing ModelType check for users without finger autoposing.

Changed the default value of Secondary Motion Floor Collision.

Improved the error message in the Add Noise script.

Improved error messages when nothing valid is selected for the Go to T-pose command.

Changed the local rotation of the model in the Roblox sample scenes.

Fixed an issue when importing certain GLB files.

Deployed the Python Stubgen files.

Updated the default scene environment.

Added a delay before showing timeline tooltips.

Fixed the Tween Machine action in the top menu.

Fixed the mesh visibility setting for MeshObject in Filament’s Reference mode.

Removed separate categories TOOLBAR_VISIBLE and VISUALIZER_VISIBLE in settings.

Separated the Collision Penetration Cleaning settings.

Redesigned the physics snapping workflow.
Snap to Physics now asks whether to apply the operation to all frames or only keyframes; applying it to all frames marks the interpolation in green, while applying it only to keyframes does not; the dependency on Fix Interpolation on Change was removed; dialogs about disabling physics sliders and the automatic disabling of the sliders were removed; the Physics Assistant button is disabled instead; after snapping, physics is applied to the gray character and disabled for the green character.

Fixed a crash during unbaking.

Fixed a crash when pasting animation from a closed scene.
