Cascadeur: AI-Powered 3D Keyframe Animation Software

Cascadeur is a dedicated 3D keyframe animation application built for anyone who needs to bring humanoid or creature characters to life with realistic, physically accurate motion. Rather than replacing an animator's craft, its AI-assisted tools speed up the tedious parts of the process—like blocking key poses and calculating secondary motion—while leaving full creative control in the artist's hands at every step. The software packs a deep toolset for professional animation work, including Trajectories, Ghosts, a Copy Tool, Tween Machine, IK/FK Interpolation, a Graph Editor, and video reference import. Combined with an AutoPhysics engine that instantly previews how a pose reacts physically, Cascadeur bridges the gap between hand-crafted keyframing and simulation, making it especially useful for fast-paced action, sports, and fighting game animation. Designed to slot into existing pipelines, Cascadeur supports FBX and DAE file interchange, letting studios and solo creators move rigged characters and finished animations between engines like Unity and Unreal or other DCC software with minimal friction.

Start by rigging your character using the Quick Rigging Tool, or import a pre-rigged model via FBX or DAE. Use the AI-assisted posing tools to quickly block out key poses, then apply AutoPhysics to preview realistic motion and weight instantly. Refine secondary motion (like hair, cloth, or follow-through) with the dedicated secondary motion tools, and fine-tune timing using the Graph Editor, Tween Machine, and IK/FK Interpolation. Import video references for accuracy, adjust with Trajectories and Ghosts for spacing, then export your finished animation in FBX, DAE, or CASC format for use in your game engine or animation pipeline.
