Input

Field	Kind	Default	Description
`prompt` required	text	—	Describe which texture to extract from the image.
`image_size`	JSON	square_hd	Output texture dimensions in pixels.
`num_inference_steps`	number (whole) 1 to 8	8	Number of denoising steps for texture generation.
`seed`	number (whole)	—	Random seed for reproducible generation.
`num_images`	number (whole) 1 to 4	1	Number of texture images to generate.
`enable_prompt_expansion`	true or false	true	Expand prompt with an LLM for richer detail. Adds ~0.0025 credits.
`tiling_mode`	one of both, horizontal, vertical	both	Tiling direction: 'both' (omnidirectional), 'horizontal', or 'vertical'.
`tile_size`	number (whole) 32 to 256	128	Tile size in latent space. Automatically capped to the generated image dimensions on tiled axes (64 = 512px, 128 = 1024px).
`tile_stride`	number (whole) 16 to 128	64	Tile stride in latent space. Automatically capped to half the effective tile size.
`image_url` required	URL or file	—	URL of the image to extract a texture from.
`strength`	number … to 1	0.6	How much to transform the input image. Only used when image_url is provided.
`maps`	list	["basecolor","normal","roughness","metalness","height"]	Which PBR maps to predict. Deselect all to skip PBR estimation entirely. Defaults to all five.
`upscale_factor`	one of 0, 2, 4	0	Upscale factor for predicted PBR maps via SeedVR seamless upscaling. 0 = no upscaling, 2 = 2× resolution, 4 = 4× resolution. The base texture image is not upscaled.
`output_format`	one of jpeg, png, webp	png	Output image format for textures and PBR maps.
