What it does
KimodoUnityBridge, a Unity package built on NVIDIA Kimodo, adds local animation generation to a project. A motion prompt becomes a clip, pose and end-effector constraints can be added, then the clip is baked, retargeted to another character and placed on Timeline. The repository ships a `SKILL.md`: the agent works in three stages, prepare, execute and verify, and calls bridge commands such as `animation.generate`, reading long jobs through `generation.get`. The runtime starts from the project itself, CUDA gives acceleration and a CPU fallback exists.
Who it is for. Unity developers and animators who hand draft humanoid animations to an agent.
Good fit when
- A draft walk or gesture clip is needed for a character with a Humanoid Animator.
- Finished animation must be retargeted to another humanoid.
- Poses from a photo or video should become a pose array for a clip.
- A clip is assembled on Timeline and settings are edited without manual recalculation.
Not a fit when
- The character is not humanoid and the project has no Humanoid Avatar.
- The machine cannot run the models: at least 8 GB of memory and disk space are required.
- You need final-quality animation without manual cleanup.
Example request
Generate a slow waving clip for the selected character, bake it and place it on a Timeline track.Limitations
Unity 2022.3 or newer and at least 8 GB of memory are required. On first launch the local runtime and models are downloaded into the project, which takes a lot of time and space. CUDA is the main acceleration path and CPU generation is slower. Logs go to `NvlabKimodoQuickServer~/log` inside the project. Weights and Kimodo model licensing follow NVIDIA terms. The package attaches to an existing Unity project and brings no editor of its own.
How to disable. Remove the `com.unity.kimodo_unity_motion_tools` package in Package Manager or `manifest.json`, then the `NvlabKimodoQuickServer~` folder with models inside the project.
FAQ
How do I install the package?
In Unity Package Manager choose Add package from git URL and enter `https://github.com/OneYoungMean/KimodoUnityBridge.git`. The same URL works as a `manifest.json` dependency.
Does generation return a result immediately?
No. `server.install` and `animation.generate` are asynchronous and return a `request_id`; read status with `generation.get`.
Where do I look for startup errors?
In `NvlabKimodoQuickServer~/log/setup.log` and `bridge_server.log` inside the Unity project.
Which platforms are supported?
Windows, macOS and Linux. CUDA is the main acceleration path and a CPU fallback exists.
What does a character need?
Humanoid workflows require the character to have a valid Humanoid Animator.

README in short
The README describes the package as a local Kimodo runtime in Unity and gives a separate section for AI agents. Bridge commands are defined in `Command/help.json`.
