TencentSmartTopologyNode - ComfyUI Built-in Node Documentation

This node performs smart retopology on a 3D model, automatically creating a new, cleaner mesh with optimized polygon count. It connects to a Tencent Hunyuan 3D API to process the model, supporting GLB and OBJ file formats up to 200MB. The node returns the processed model as an OBJ file.

Inputs

Parameter	Description	Data Type	Required	Range
`model_3d`	Input 3D model (GLB or OBJ). The file must be in GLB or OBJ format and cannot exceed 200MB.	FILE3D	Yes	-
`polygon_type`	Surface composition type.	STRING	Yes	`"triangle"` `"quadrilateral"`
`face_level`	Polygon reduction level.	STRING	Yes	`"medium"` `"high"` `"low"`
`seed`	Seed controls whether the node should re-run; results are non-deterministic regardless of seed. (default: 0)	INT	No	0 to 2147483647

Note: The seed parameter is used to trigger a re-run of the node, but the final output is not guaranteed to be the same for the same seed value.

Outputs

Output Name	Description	Data Type
`OBJ`	The processed 3D model with optimized topology, returned in OBJ format.	FILE3D
