MeshyTextToModelSmartTopologyNode - ComfyUI Built-in Node Documentation - ComfyUI

This node generates a game-ready triangle mesh at a target face count with Meshy T2.5. The topology is built at the requested polycount instead of being decimated afterwards, so the result is ready for a game engine without a separate retopology pass.

Inputs

Parameter	Description	Data Type	Required	Range
`model`	The Meshy model version to use for generation.	COMBO	Yes	`"meshy-t2.5"`
`prompt`	The text description of the 3D model to generate.	STRING	Yes	1 to 800 characters
`target_polycount`	Approximate number of triangles in the generated mesh. Default: 15000.	INT	Yes	100 to 30000
`pose_mode`	The pose of the generated character. An empty string requests no specific pose. This is an advanced setting. Default: `""` (empty string).	COMBO	Yes	`""` `"A-pose"` `"T-pose"`
`seed`	Seed controls whether the node should re-run; results are non-deterministic regardless of seed. Default: 42.	INT	Yes	0 to 2147483647

Constraints:

The prompt must contain between 1 and 800 characters.
target_polycount is the number of triangles the mesh is built from, not a limit applied after generation.

Outputs

Output Name	Description	Data Type
`meshy_task_id`	The unique identifier of the Meshy API task.	MESHY_TASK_ID
`GLB`	The generated 3D model in GLB format.	FILE3DGLB
`FBX`	The generated 3D model in FBX format.	FILE3DFBX
