What it does

Cascadeur is a 3D animation tool for character work. It offers AI inbetweening, AutoPosing, ragdoll physics and AutoPhysics, plus rigging and retargeting for humanoids and quadrupeds. It works with .FBX, .DAE, .GLB/.GLTF and .USD files. A free plan is available for non-commercial use with export limited to .casc.

Cascadeur is a 3D animation tool built around keyframe work. Its inbetweening tool uses AI interpolation to generate motion between keyframes. AutoPosing lets you get natural poses by moving fewer control points. Ragdoll is a procedural tool for impacts, falls and collisions, while AutoPhysics shows a physically accurate result and helps adjust secondary motion and inertia. The software also covers rigging for humanoids and quadrupeds, retargeting between characters with different skeletons, and a live link that streams animation to Unreal Engine. It works with .FBX, .DAE, .GLB/.GLTF and .USD files. The free plan is for non-commercial use and exports only to .casc. Paid plans add .fbx and .dae export, and the Pro plan adds commercial use, retargeting, scene linking and quadruped AutoPosing. The pricing page lists Indie at 19 euros per month or 8 euros per month billed annually, and Pro at 49 euros per month or 33 euros per month billed annually. Yearly Indie and Pro licenses include access to perpetual license builds. The site does not state whether an API or open source version exists.
