Direct answer
What is Cascadeur?
Cascadeur is a standalone 3D animation software program designed to create, edit, and clean up character motions using AI-assisted posing and physical simulation.
Developed by Nekki Limited, Cascadeur is desktop software designed for 3D character animation, motion capture (mocap) cleanup, and physics-driven motion synthesis. Rather than replacing the animator with black-box generation, it integrates AI posing and dynamic physics directly into standard keyframing workflows. Key features include AutoPosing, an AI system that predicts natural posture based on moving a minimal number of control points, and AutoPhysics, which calculates physically accurate trajectories, secondary motion, and inertia without requiring manual tweaking of every curve. Animators can also leverage AI inbetweening, procedural ragdoll simulations for collisions and falls, and animation unbaking to clean up dense mocap data, resolve foot sliding, and fix knee popping. Cascadeur supports humanoid characters and quadrupeds, with automatic joint-based rigging, retargeting across diverse skeletal topologies, and live streaming to Unreal Engine via UE Live Link. The software exports to standard 3D formats including FBX, DAE, GLTF/GLB, and USD (available on paid plans), allowing seamless integration into major game engines and DCC packages.
Unlike traditional keyframing suites or prompt-to-video generators, Cascadeur combines physical constraint simulation (AutoPhysics) with editable AI posing and mocap unbaking, letting artists retain frame-by-frame control while physics and machine learning automate weight and timing.
Product capabilities
Key features
AutoPhysics
Simulates physical forces and displays a character double to calculate realistic weight shifts, secondary motion, trajectories, and inertia.
AI AutoPosing
Suggests natural full-body poses for humanoids, quadrupeds, and fingers by manipulating a minimal set of control points.
Animation Unbaking & Mocap Cleanup
Converts dense baked animation files into editable keyframes, resolving common capture defects like foot sliding, knee popping, and geometry clipping.
AI Inbetweening
Interpolates movement between keyframes using machine learning to produce smoother, more natural transitions.
Quick Rigging & Retargeting
Enables drag-and-drop joint assignment for humanoid and quadruped auto-rigging, alongside retargeting between dissimilar skeletal structures.
Unreal Engine Live Link
Streams viewport animation data directly into Unreal Engine in real time, updating scenes dynamically as adjustments are made.
Procedural Ragdoll & Collision
Applies procedural physical dynamics to simulate falls, impacts, and environmental collisions non-destructively.
Practical fit
Who should use Cascadeur?
Indie Game Combat & Action Animation
Keyframing complex acrobatics, jumps, and combat moves while relying on AutoPhysics to ensure believable gravity and center of mass.
Motion Capture Post-Processing
Importing raw mocap data, unbaking the intervals, and polishing foot plants and jitter using animation layers and AutoPosing.
Quadruped Character Rigging & Animation
Quickly setting up rigs and quadruped AutoPosing for four-legged creatures like horses, cats, and dogs.
MetaHuman Previsualization in Unreal Engine
Iterating on character gestures and previews in Cascadeur while seeing synchronized updates directly in Unreal Engine via Live Link.
Editorial assessment
Pros and limitations
Where it is strong
- Deeply grounded physics engine calculates weight and trajectory without manual curve hunting
- Yearly subscriptions automatically convert to perpetual licenses for versions released during the active term
- Fast mocap unbaking tool makes raw motion data manageable and editable with keyframes
- Live Link integration with Unreal Engine provides instant viewport synchronization
Where to be careful
- Free plan exports strictly to the proprietary .casc file format, blocking direct pipeline export to FBX or USD
- macOS version is limited strictly to Apple Silicon (ARM) chips; Intel x86 Macs are unsupported
- Indie license eligibility is restricted to entities with under $100,000 in annual revenue
Commercial context
Cascadeur pricing
At the review date, Nekki offers a free non-commercial tier (export limited to .casc format), an Indie subscription ($19/month or $96/year for creators earning under $100k/year), and Pro/Teams tiers ($49/month or $396/year). Annual Indie and Pro plans grant a perpetual fallback license to versions released during the active period. Prices exclude local taxes; check the official pricing page for currency options and current promotions.
Pricing, limits, taxes, model access, and regional availability can change. Verify the purchase-critical details on the official pricing page linked under Sources.

Frequently asked
Cascadeur FAQ
Can I export FBX or USD animations using the free plan?+
No. The Free plan only allows saving in the proprietary .casc file format. Exporting to standard formats such as FBX, DAE, USD, and GLTF requires an Indie, Pro, Teams, or Educational subscription.
Does Cascadeur offer perpetual licenses?+
Yes. Every annual (Yearly) Indie and Pro license converts into a perpetual license after completing the 12-month term, allowing continued use of any major versions and hotfixes released during the active period.
What are the eligibility criteria for the Indie plan?+
The Indie plan permits full commercial use as long as the licensee's aggregate gross revenue or funding from all sources is less than $100,000 per year.
What operating systems are supported by Cascadeur?+
Cascadeur supports 64-bit Windows 10 (version 1809+) and Windows 11, Linux (Ubuntu 20.04 or later), and macOS (version 13.3 or later on Apple Silicon M-series chips). Intel-based x86 Macs are not supported.
Can single licenses be installed on multiple machines?+
Yes. A single Cascadeur seat can be installed and activated on up to three desktop devices, but the software cannot be used simultaneously across multiple computers under the same license.
