2025.3

Filament

Filament is the brand-new rendering engine that Cascadeur now uses to visualize scenes in the Viewport. It supports advanced rendering techniques such as environment lighting, shadows and ambient occlusion.
These settings are available in the Visible/Selectable menu, in its View part:

Simple Textures have been replaced with Materials: a more complex and lifelike way to render 3D objects. It supports separate textures for color, roughness etc.
Also, now when you import FBX files to your scenes, materials from these files will be imported as well.

Note

In the version 2025.3, Filament is an experimental feature. To use it, you’ll have to download a separate install file. It is also Windows-only at the moment, and lacks some of the functionality such as Ghosts or Linked Scenes.
In the future, Filament will be available in the main version of Cascadeur on all platforms.

Reworked Inbetweening

Inbetweening received a major overhaul:

Now, Inbetweening is considered to be a type of interpolation.

The Inbetweening button has been moved to the Interpolation menu on the Timeline:

The Style option (previously found on the Scene Settings panel) is now available right on the Timeline through the context menu.
By right-clicking the Timeline, you open this menu, and there you can use the AI description list to set the style for the animation:

This allows for more precise control over the resulting animation.

For example, you can set Inbetweening only for specific Animation Tracks while using regular interpolation for the others.

And if you make any changes to the animation - such as creating additional keyframes - you won’t need to manually reset Inbetweening, it will update automatically. For this, there is the Update Inbetweening option on the Inbetweening tab of the Scene Settings panel. This option is enabled by default:

On the same panel, there is also the option for applying Fulcrum Motion Cleaning to Inbetweening animation.

Note

Using Inbetweening the old way is still an option as well: for this, there’s the Inbetweening item in the Timeline menu. In the same menu, you can also set the Style for the animation generated by this version of Inbetweening.

Quadrupeds Support

Cascadeur now supports quadruped (four-legged) characters in several ways:

AutoPosing now correctly recognizes such characters and can be used to pose them.

Quick Rigging Tool now has the Quadruped tab for rigging such characters:

Physics Updates

Improved character interaction in AutoPhysics.

Added angle limits for Ragdoll.
In the current version, these limits can be made visible by turning on the Angle Constraints setting in the Setting Window → Visualizers Visible.
Constraints themselves are set up on the Angle Constraint tab of the Object Properties panel.

Rigging Updates

Quick Rigging Tool now supports Twist and Untwist bones.
For this, there is a dedicated tab called Twists:

In this tab, you can set Joints to be used as twist bones - and also mark them as untwist bones (using the Untwist radio button).
There are eight twists available: two per each limb. Additional twists - if your rig needs them - can be created using regular Rigging Tools.

This functionality is useful when rigging complex characters such as ones from Daz Studio or Character Creator.

Other Updates

Added context menu for the Timeline.
It can be used for setting interpolations, adding/removing keyframes and changing styles for Inbetweening.

Improved GLB/GLTF import.
More options (similar to FBX import), and support for VRM format.

Improved Scene Linking Tool.
Added new options for customizing linked scenes.
Also improved Linked Scene start frame sync.

Improved Camera Objects.
Camera objects can now be imported from and exported to FBX files (and other file formats). Camera settings have also been reworked to be more comprehensive and versatile. And when you copy/paste a Camera, its parameters are copied/pasted as well.
Also, Camera copying with additional data like AoV has been enhanced.

Improved performance for long animations.

You can now resize animations while retaining keyframes.

Fixes

Fixed RecursionError during Center of Mass creation.

Fixed scene import error with constraints.

Fixed default cube object issues.

Fixed the issue with multiple joints between Quick Rigging Tool chest and neck not always included in generated Spline IK.

Fixed SpaceMouse navigation limited to the most recent file when multiple files open.

Fixed SpaceMouse zoom in orthographic viewports.

Fixed extremely slow SpaceMouse panning in orthographic viewports.

Fixed crash when opening scene with camera tracking tool object.

Fixed import error when 'Follow rotation' is on in the Root Constraint.

Added reverse IK behavior (from child to parent points).

Added ‘keep main point on parent track’ option.

Locked proto collision scale.
