Cascadeur

What is Cascadeur?

Cascadeur is a 3D character animation tool built around physics. Instead of spending hours tweaking keyframes so a character lands, hits or reacts believably, you pose the character and let the software's AI solve the physical result: weight, momentum, balance and contact with the ground.

It comes from Nekki, the game studio behind the Shadow Fight series, which needed a faster way to animate fighters. The tool grew out of that internal need and became a standalone product used by game studios and VFX houses for both keyframe animation and cleaning up motion capture data.

The core idea is a physics-aware workflow: you specify a few key poses and the Auto-Physics feature fills in the motion in a way that looks physically plausible, which helps even novice animators produce believable movement.

Key Features

• Auto-Physics: AI-assisted simulation of weight, inertia and balance on your poses
• Auto-Pose: one-click natural posing of character skeletons
• Keyframe assistant for cleanup and re-timing of keyframes
• Motion capture retargeting and cleanup for mocap data
• Rigid body and cloth simulation tools
• Export to common formats like FBX and Alembic for use in other pipelines
• A free non-commercial version for learning and personal projects

How to get started

Download Cascadeur from the official website, create a free account, and install it on Windows, macOS or Linux. The free version is enough to learn the whole workflow.

The interface centers on the viewport and a set of AI tools. You import a character rig or a scene, pose the skeleton, and press Auto-Physics to see the motion simulated. Nekki's YouTube channel and the built-in tutorials walk you through your first animations.

• Download and install Cascadeur from the official site
• Create a free account to unlock the non-commercial version
• Import a character or build a simple rig
• Pose a keyframe and use Auto-Physics to simulate the movement
• Export the result as FBX or Alembic into your game engine or editor

Use cases

• Keyframe animation for game characters, especially fighting and action moves
• Cleaning up and fixing motion capture takes
• Physics-accurate stunt and combat animation without mocap equipment
• Previsualizing tricky physical interactions like jumps, throws and impacts
• Learning animation principles with instant physical feedback

Pricing and licensing

Cascadeur is proprietary software with a free tier for non-commercial use and paid subscriptions for commercial work. The free version covers learning and personal projects; professional pricing depends on the plan and region.

Check the official website for the current plans, since Nekki adjusts pricing and the feature split between free and paid versions from time to time.

Pros and cons

The physics simulation is the standout: it produces weighty, believable motion far faster than traditional keyframing, and the tools are genuinely approachable for beginners. The export pipeline slots into Unreal, Unity and Blender workflows.

The trade-offs are that you still need to pose and direct the character yourself, very stylized or cartoony motion can fight the physics solver, and some features are reserved for paid tiers.
