The Meshy: Rig Model node takes a 3D model from a previous Meshy task and automatically creates a skeleton for it, producing a rigged character that can be posed and animated. The node outputs the rigged model in both GLB and FBX file formats.

Inputs

Parameter	Data Type	Required	Range	Description
meshy_task_id	STRING	Yes	N/A	The unique task ID from a previous Meshy operation (e.g., text-to-3D or image-to-3D) that generated the model to be rigged.
height_meters	FLOAT	Yes	0.1 to 15.0	The approximate height of the character model in meters. This aids in scaling and rigging accuracy (default: 1.7).
texture_image	IMAGE	No	N/A	The model’s UV-unwrapped base color texture image.

Note: The auto-rigging process is currently not suitable for untextured meshes, non-humanoid assets, or humanoid assets with unclear limb and body structure.

Outputs

Output Name	Data Type	Description
model_file	STRING	A legacy output for backward compatibility, containing the filename of the GLB model.
rig_task_id	STRING	The unique task ID for this rigging operation, which can be used to reference the result.
GLB	FILE3DGLB	The rigged 3D character model saved in the GLB file format.
FBX	FILE3DFBX	The rigged 3D character model saved in the FBX file format.
