Input Parameters

Name	Type	Description	Default	Constraints
`enable_pbr`	boolean	Enable PBR (Physically Based Rendering) material generation.	`false`	—
`face_count`	integer	Number of faces (polygons) in the generated 3D model.	`500000`	min: 40000, max: 1500000
`generate_type`	string	Type of 3D generation. 'Normal' generates textured model, 'Geometry' generates white model without textures (EnablePBR has no effect).	`"Normal"`	Normal Geometry
`image`	string (uri)	Input image to convert to 3D. Either prompt OR image must be provided, but not both. Recommendations: simple background, no text, single object, object occupies >50% of frame. Supported formats: jpg, png, jpeg, webp. Resolution: 128-5000px per side, max 6MB.	`—`	—
`prompt`	string	Text description of the 3D model to generate. Either prompt OR image must be provided, but not both. Supports up to 1024 characters.	`—`	—
