Cascadeur

Cascadeur is a 3D keyframe animation tool with AI-assisted physics and posing built in. Its AutoPosing system, driven by neural networks, helps animators create physically plausible poses faster — and AutoPhysics adds secondary motion like cloth and hair dynamics without manual simulation setup.

Character animators for games and film use it to clean up mocap data, build action sequences, and iterate on fight choreography without the slow feedback loop of traditional keyframe software. It imports FBX, DAE, and USD files, making it compatible with assets from Maya, Blender, and most game engines.

The tool has a steeper learning curve than consumer-grade animation apps. It's designed for animators who already understand rigging and keyframe principles — not beginners looking for push-button animation. A free tier is available with full feature access; paid plans add cloud rendering and commercial licensing options.
