CASC File Format Explained

What It Stores

The format stores skeletal hierarchy, joint rotations, character rig data, and baked or keyframed animation sequences. It also stores physics-related data used internally by Cascadeur, such as center of mass calculations and motion balancing.

Primary Use Cases

• Storing character animation sequences as part of a game development workflow.
• Saving scenes that include physics-assisted action and stunt-style animations.
• Exporting animation data (typically via FBX or similar formats) to external DCC applications.

Strengths

• Retains native physics data and control rig behaviors.
• Optimized for seamless iteration inside Cascadeur.
• Preserves animation timing, transitions, and constraint behavior within Cascadeur.

Limitations

• Restricted ecosystem with limited direct support outside Cascadeur.

Common Software Support

Supported natively within Cascadeur. Export pipelines allow animation data to be transferred via FBX for integration into tools like Autodesk Maya, Blender, and game engines such as Unreal Engine and Unity.
