stabilityai/stable-diffusion-xl-base-1.0 for PBR material generation from height maps.
The model generates a 4-channel output, corresponding to a 3-channel BaseColor map and a 1-channel Roughness map.
You can find some example images below. For each prompt, the grid shows the input height map, followed by the generated BaseColor map(s) and then the generated Roughness map(s).a photorealistic, highly detailed photograph of a lunar surface material

# TODO: add an example code snippet for running this diffusion pipeline
