Input Schema

11 parameters · 1 required · 10 optional

Parameter	Type	Required	Description
`image`	string	Required	URL of the reference image for texturing
`seed`	integer	Optional	Random seed for reproducibility
`mesh_url`	string	Optional	URL of the untextured 3D mesh to retexture. Supports GLB, OBJ, PLY, and STL formats.
`resolution`	integer	Optional	Internal resolution for texture generation. Higher produces finer texture details but is slower. · Options: 512, 1024 · Default: 1024 5121024
`texture_size`	integer	Optional	Resolution of the texture image baked onto the mesh. Higher values capture finer surface details but produce larger files. · Options: 1024, 2048, 4096 · Default: 2048 102420484096
`tex_slat_rescale_t`	number	Optional	Controls noise schedule sharpness for texture generation. Higher values produce sharper texture details. · Min: 1 · Max: 6 · Default: 3
`tex_slat_sampling_steps`	integer	Optional	Number of denoising steps for texture generation. More steps = slower but potentially cleaner textures. · Min: 1 · Max: 50 · Default: 12
`tex_slat_guidance_rescale`	number	Optional	Dampens artifacts from high guidance in the texture stage. Increase if textures look noisy or have color banding. · Min: 0 · Max: 1 · Default: 0
`tex_slat_guidance_strength`	number	Optional	How closely the texture follows the input image colors. Higher values produce more vivid but potentially oversaturated textures. · Min: 0 · Max: 10 · Default: 1
`tex_slat_guidance_interval_end`	number	Optional	Fraction of the denoising process at which classifier-free guidance ends for the texture stage. Must be >= tex_slat_guidance_interval_start. · Min: 0 · Max: 1 · Default: 0.9
`tex_slat_guidance_interval_start`	number	Optional	Fraction of the denoising process at which classifier-free guidance starts for the texture stage. Guidance is only applied between interval_start and interval_end. · Min: 0 · Max: 1 · Default: 0.6

Output Schema

Field	Type	Description
`id`	string	Unique identifier for the generation task
`status`	string	Task status: pending, running, completed, failed, timeout
`model`	string	Model used for the generation
`outputs`	array	Array of output items
`outputs[].url`	string	URL of the generated artifact
`outputs[].content_type`	string	MIME type (e.g. image/png, video/mp4)
`error`	object \| null	Error details if failed, null on success
`error.type`	string	Machine-readable error type code
`error.message`	string	Human-readable error description

Async Workflow

This model uses asynchronous execution. Submit a request and poll for the result.

Submit — POST to /v1/run, receive an id
Poll — GET /v1/run/{id} until status is completed, failed, or timeout
Retrieve — Read outputs from the completed response
