Cascadeur

What is a Cascadeur?

Cascadeur is an independent 3D keyframe character animation software developed by Nekki; it allows for the creation of new animations, as well as for the cleanup and editing of imported motion capture or asset animations. It combines traditional manual control with AI-driven posing, AI interpolation, and physics-based motion correction.

The software focuses on animation and character skeletons; it is not a complete solution for modeling, texturing, rendering, or game development. In practice, it is usually used in conjunction with tools such as Blender, Maya, Unreal Engine, Unity, or other 3D software.

A one-sentence summary

Cascadeur is a cross-platform software that utilizes AI for pose setting, intelligent interpolation, and physical correction to accelerate the creation of keyframe animations for 3D characters.

Main functions

AutoPosing intelligent pose setting

AutoPosing uses machine learning to predict the body poses desired by the animator. When the user moves a few control points, the system adjusts the other parts of the body accordingly, but the final pose can still be adjusted manually.

Posing of fingers and four-legged characters

Smart finger controllers can simplify gestures and grasping actions. Advanced solutions such as Pro also offer AutoPosing for quadruped characters, which is useful for creating the poses of animal characters.

AI Inbetweening

AI interpolation can automatically generate intermediate movements based on the key poses set by the user. It is suitable for starting, stopping, turning, and creating cyclic transitions; after it has been generated, it is still necessary to check for issues such as foot slippage, overlapping joints, and rhythm.

AutoPhysics

AutoPhysics analyzes the created animation and provides a version that is more in line with physical laws. This tool strives to preserve the original intent of the movements, while improving the center of gravity, trajectory, momentum, and points of force application.

Environmental interaction

Advanced physics tools enable characters to interact with the ground, walls, and other objects. If the settings for contact points, support surfaces, and collision volumes are incorrect, the physical behavior may also appear unnatural.

Secondary action

Users can add effects such as vibration, rebound, and overlap to actions like waiting, jumping, and attacking. Such adjustments can enhance the vitality of these actions, but excessive intensity can undermine the sense of weight of the character.

Animation unbaking

Animation Unbaking allows for converting animated sequences that contain keys for each frame into versions with fewer keyframes and editable interpolation intervals. This feature is particularly useful for cleaning up motion capture data, store animations, and assets exported from engines.

Animation redirection

Redirection allows animations to be transferred to characters with different proportions or skeletal structures. The source character and the target character must have proper bone mapping established, and hand and foot contacts need to be adjusted after the transfer.

Quick binding

Users can drag and drop character joints to create control bindings suitable for the Cascadeur tool. Standard skeletons can be bound with just one click, while non-standard characters require verification of their axes, naming, and deformation results.

Addition animation layer

Version 2026.2 introduces an addition animation layer in the Alpha phase, which allows for the layered application of corrections to different movements. This feature is still in its early stages; it is important to keep backups and test exports for critical projects.

How do AI tools determine their position?

The AI in Cascadeur primarily assists with posing and the transitions between keyframes; it does not generate the entire 3D film directly from text. Animators remain responsible for determining the camera targets, key poses, timing, character personality, and the overall quality of the animation.

The developers state that the AI tools are trained using Nekki’s own animation data, as well as third-party animation data that has been legally purchased and verified as suitable for use by AI. This does not mean that users can pass on the training data or models.

Supported import/export and workflows

Which users are it suitable for

• Game animator: Creates animations for battles, movements, standby states, and transitions.
• Independent developers: Create character animation workflows at a lower cost.
• 3D short video creator: Quickly create key poses and physical transitions.

• Mobile creators: Edit animations on iPhone, iPad, or Android devices.

Desktop version packages and prices

As of August 24, 2026, Cascadeur’s public desktop plans include Free, Indie, Pro, Teams, and Educational. Monthly, annual, promotional prices, as well as taxes and regional pricing, may vary; the final details are subject to the settlement page and licensing terms.

Pro and Teams offer a 14-day trial period for free, but the details regarding the trial benefits and payment information must be confirmed at the time of activation. As for the Educational version, whose price is $49, the billing cycle is not specified in the official FAQs; schools should refer to the actual pricing provided.

Annual subscription for the permanent version

Indie and Pro subscribers, with an annual subscription, can obtain a permanent license version after a minimum period of 12 months. Even after the subscription ends, they can continue to use the versions that were released during the subscription period and are listed in their account, but they will no longer receive subsequent versions or personal support.

Price for mobile version

Cascadeur Mobile can be downloaded for free on iPhone and iPad, with paid features available through in-app purchases. As of the date of verification, the Pro version costs $7.99 per month or $49.99 per year on the US App Store; availability and prices on Android vary depending on the respective app stores.

The purchasing options for mobile and desktop devices may differ in terms of functionality and account benefits. It is necessary to check on the account and payment page whether cross-platform sharing is available before making a purchase; one should not rely solely on the same product name to draw conclusions.

System requirements

The minimum requirements for the desktop version also include a frequency of 2.4 GHz or higher, as well as a GPU such as the NVIDIA GTX 550 Ti or one that supports OpenGL 3.3. The minimum specifications are only sufficient for basic operation; longer animations, multiple characters, and high-resolution meshes require more memory and better graphics performance.

Getting started guide

1. Select the license based on commercial needs, revenue scale, export format, and team size.
2. Install the version corresponding to your system, log in to your account, and activate your seat.
3. Create a new scene, or import characters with skeletons and animations.
4. Use the quick binding tool to create a Cascadeur controller.
5. Set the main key poses and action rhythms on the timeline.
6. Use AutoPosing to correct the pose, and then employ AI interpolation to create transitions.
7. Enable AutoPhysics to view physical suggestions, accepting only those that are in line with the creative intent.
8. Check the trajectory, pivot points, center of gravity, foot sliding, interweaving, and rhythm of the movements.
9. Select the preset export option for the target software, and then read it back in the target engine or DCC software to verify it.

Motion capture cleanup process

1. Import the baked animation using the correct frame rate, units, and axis.
2. Map the source skeleton to the target character and complete the redirection.
3. Use Animation Unbaking to identify keyframes and interpolation intervals.
4. Manually correct foot slipping, hand contact issues, joint jumps, and vibrations.
5. Use trajectories and ghost images to compare the original action with the edited result.
6. Use AutoPhysics to improve momentum when necessary, while preserving the performance characteristics.
7. Fix the root bone, cyclic boundaries, frame rate, and desired tracks before exporting.
