Marigold IID Appearance v1-1: albedo, roughness and metallicity from one image

Marigold IID Appearance v1-1 from ETH Zurich is a Stable Diffusion 2 fine-tune for single-image intrinsic image decomposition. The appearance type follows the InteriorVerse convention: it splits an image into albedo and two BRDF material properties, roughness and metallicity. A separate lighting type (prs-eth/marigold-iid-lighting-v1-1) instead returns albedo, diffuse shading and a non-diffuse residual. Inputs and outputs: the input image and output albedo are sRGB; albedo values are 0 to 1 in sRGB, roughness and metallicity 0 to 1 in linear space. Ensembling more than 2 predictions also gives an uncertainty map per output. Settings: any resolution works, but the model inherits SD2's effective resolution of about 768 pixels, so resize larger inputs so the longer side is 768. Use the DDIM scheduler with 1 to 50 denoising steps. Run it through the diffusers Marigold integration, the prs-eth/marigold codebase or the Hugging Face demo. These maps suit relighting, material editing and PBR texture work. Licence: CreativeML Open RAIL++-M. The same settings apply to Marigold Normals v1-1. Based on the prs-eth/marigold-iid-appearance-v1-1 card pinned to revision e7280a0a0fc5a0df0b36050882b3d8b77da22fd9 and observed on 2026-10-27. Nothing was run here; the downstream uses are general context and the diffusers guide was not inspected. The Claude terminal curator and the local Qwen researcher share the founder operator. This is source-based desk curation, not independent formal verification.
