Patina PBR Material Maps - ComfyUI Built-in Node Documentation - ComfyUI

Derives a set of PBR material maps from an existing texture image: basecolor, normal, roughness, metalness and height. Enable only the maps you need, since each enabled map adds to the cost. Use it to complete a texture that has no material maps yet, or to rebuild a single broken map.

Inputs

Parameter	Description	Data Type	Required	Range
`image`	The photograph or render to derive the PBR maps from.	IMAGE	Yes	-
`basecolor`	Generate the basecolor (albedo) map. Default: True.	BOOLEAN	Yes	true false
`normal`	Generate the normal map. Default: True.	BOOLEAN	Yes	true false
`roughness`	Generate the roughness map. Default: False.	BOOLEAN	Yes	true false
`metalness`	Generate the metalness map. Default: False.	BOOLEAN	Yes	true false
`height`	Generate the height (displacement) map. Default: False.	BOOLEAN	Yes	true false
`seed`	Seed for reproducible denoising. Default: 42.	INT	Yes	0 to 2147483646
`safety_checker`	Run the provider’s content safety check on the request. Advanced setting. Default: False.	BOOLEAN	Yes	true false
`auto_downscale`	Automatically downscale an input image whose longest side exceeds 2048 pixels, the model’s input limit, preserving the aspect ratio; smaller images are left as they are. Disable it to raise an error on oversized images instead. Advanced setting. Default: True.	BOOLEAN	No	true false

Constraints and behavior:

At least one map must be enabled, otherwise the run fails.
The input image is limited to 2048 pixels on its longest side; either let auto_downscale shrink it or the run fails on an oversized image.
Each map that is disabled still returns an output, but as a 1x1 placeholder image, so only connect the outputs you actually generated.

Outputs

Output Name	Description	Data Type
`basecolor`	The generated basecolor (albedo) map, or a 1x1 placeholder when that map is disabled.	IMAGE
`normal`	The generated normal map, or a 1x1 placeholder when that map is disabled.	IMAGE
`roughness`	The generated roughness map, or a 1x1 placeholder when that map is disabled.	IMAGE
`metalness`	The generated metalness map, or a 1x1 placeholder when that map is disabled.	IMAGE
`height`	The generated height (displacement) map, or a 1x1 placeholder when that map is disabled.	IMAGE
