Inputs
| Parameter | Description | Data Type | Required | Range |
|---|---|---|---|---|
model | The version of the Hunyuan3D model to use. The LowPoly option is unavailable for the 3.1 model. | COMBO | Yes | "3.0""3.1" |
prompt | The text description of the 3D model to generate. Supports up to 1024 characters. | STRING | Yes | - |
face_count | The target number of faces for the generated 3D model. Default: 500000. | INT | Yes | 3000 - 1500000 |
generate_type | The type of 3D model to generate. The available options and their associated parameters are: - Normal: Generates a standard model. Includes a pbr parameter (default: False).- LowPoly: Generates a low-polygon model. Includes polygon_type ("triangle" or "quadrilateral") and pbr (default: False) parameters.- Geometry: Generates a geometry-only model. | DYNAMICCOMBO | Yes | "Normal""LowPoly""Geometry" |
seed | A seed value for the generation. Results are non-deterministic regardless of seed. Setting a new seed controls whether the node should re-run. Default: 0. | INT | No | 0 - 2147483647 |
generate_type parameter is dynamic. Selecting "LowPoly" will reveal additional inputs for polygon_type and pbr. Selecting "Normal" will reveal an input for pbr. Selecting "Geometry" will not reveal any additional inputs.
Constraint: The "LowPoly" generate type cannot be used with the "3.1" model.
Outputs
