# TripoRetargetNode - ComfyUI Built-in Node Documentation

> The TripoRetargetNode applies a preset animation to an existing rigged 3D model.

The TripoRetargetNode applies a preset animation to an existing rigged 3D model. It takes the task ID of a model that was previously rigged, sends a retarget request to the Tripo API, and downloads the resulting animated file. The animated model can be returned as GLB or FBX, with optional mesh geometry and optional in-place playback.

| `original_model_task_id` | The task ID of the previously rigged 3D model to retarget.

Note: Animations in the `preset:*` group work with both rig models, while animations in the `preset:biped:*` group require a rig made with model v1.0-20240301. If the referenced rig was created with the Mixamo spec and a model version starting with `v1.0`, the retargeting call fails with an error.
