PATINA Image to Maps

Predict seamless PBR maps (base color, normal, roughness, metalness, height) from an existing texture or photo. The source image is analyzed, not rewritten.

Model ID: model_patina

Capabilities: img2img

LLM Markdown: https://app.scenario.com/api/models/model_patina/markdown

Parameter	Type	Required	Default	Min	Max	Allowed Values	Description
image	file	Yes	-	-	-	-	A flat texture or photo of a surface. PATINA predicts PBR maps from it without changing the original.
maps	string_array	No	basecolor,normal,roughness,metalness,height	-	-	basecolor, normal, roughness, metalness, height	Which PBR maps to generate. Defaults to all five.
seed	number	No	-	0	2147483647	-	A number that makes results repeatable. Reusing the same seed and settings produces the same maps; leave it empty for a different result each time.

PATINA Material

Generate a seamlessly tiling PBR material from a text prompt, with optional image-to-image variations and inpainting. Outputs a texture plus base color, normal, roughness, metalness, and height maps, up to 8K with upscaling.

LLM Markdown: https://app.scenario.com/api/models/model_patina-material/markdown

Parameter	Type	Required	Default	Min	Max	Allowed Values	Description
prompt	string	Yes	-	-	-	-	Text description of the material to generate, for example weathered copper patina or mossy stone wall.
image	file	No	-	-	-	-	An optional starting texture. Without a mask, PATINA creates variations. With a mask, it inpaints the marked region.
imageStrength	number	No	0.6	0.01	1	-	How much to transform the input image. Higher values change it more. Only used when an image is provided.
mask	file	No	-	-	-	-	A black-and-white mask for inpainting. White regions are regenerated, black regions are preserved. Requires an input image.
width	number	No	1024	512	2048	-	Output width in pixels. Upscaling applies to PBR maps only, not the base texture.
height	number	No	1024	512	2048	-	Output height in pixels. Upscaling applies to PBR maps only, not the base texture.
maps	string_array	No	basecolor,normal,roughness,metalness,height	-	-	basecolor, normal, roughness, metalness, height	Which PBR maps to predict. Deselect all to skip PBR estimation and only generate the texture.
upscaleFactor	number	No	0	-	-	0, 2, 4	Seamless upscale for predicted PBR maps. 0 keeps map resolution, 2 doubles it, 4 quadruples it (up to 8K from a 2048 texture). The base texture is not upscaled.
tilingMode	string	No	both	-	-	both, horizontal, vertical	Which directions the material repeats seamlessly. Both repeats in every direction; Horizontal repeats left-to-right; Vertical repeats top-to-bottom.
numOutputs	number	No	1	1	4	-	Number of texture images to generate from the same prompt.
numInferenceSteps	number	No	8	1	8	-	Number of denoising steps for texture generation. Higher values take longer.
enablePromptExpansion	boolean	No	true	-	-	-	Expand the prompt with an LLM for richer material detail.
tileSize	number	No	128	32	256	-	Seamless-tiling window in latent space. 64 ≈ 512px, 128 ≈ 1024px, 256 ≈ 2048px. Match this to the output resolution for cleaner repeats.
tileStride	number	No	64	16	128	-	How far the tiling window steps between passes. Smaller than tile size adds overlap and usually smoother seams; larger is faster but can show a grid.
seed	number	No	-	0	2147483647	-	A number that makes results repeatable. Reusing the same seed and settings produces the same material; leave it empty for a different result each time.

PATINA Material Extract

Extract a clean, seamlessly tiling PBR material from a photo of a real surface. Isolates the chosen material, flattens it, and predicts base color, normal, roughness, metalness, and height maps.

Parameter	Type	Required	Default	Min	Max	Allowed Values	Description
prompt	string	Yes	-	-	-	-	Describe which material to extract from the photo, for example the brick wall or the wooden floor.
image	file	Yes	-	-	-	-	A photo that contains the material you want. Perspective, shadows, and surrounding scene are flattened into a seamless texture.
imageStrength	number	No	0.6	0.01	1	-	How much to transform the extracted material while making it tileable. Higher values change it more.
width	number	No	1024	512	2048	-	Output width in pixels. Upscaling applies to PBR maps only, not the base texture.
height	number	No	1024	512	2048	-	Output height in pixels. Upscaling applies to PBR maps only, not the base texture.
maps	string_array	No	basecolor,normal,roughness,metalness,height	-	-	basecolor, normal, roughness, metalness, height	Which PBR maps to predict. Deselect all to skip PBR estimation and only extract the texture.
upscaleFactor	number	No	0	-	-	0, 2, 4	Seamless upscale for predicted PBR maps. 0 keeps map resolution, 2 doubles it, 4 quadruples it (up to 8K from a 2048 texture). The base texture is not upscaled.
tilingMode	string	No	both	-	-	both, horizontal, vertical	Which directions the extracted material repeats seamlessly. Both repeats in every direction; Horizontal repeats left-to-right; Vertical repeats top-to-bottom.
numOutputs	number	No	1	1	4	-	Number of texture variations to extract from the same photo.
