Estimating Physically-Based Material Representations from Diffusion-Generated Lighting Variations
Recovering physically-based material properties (albedo, roughness, metallic) from a single photograph is a classic ill-posed problem: any dark pixel could be a dark surface or a poorly-lit one. Prior diffusion-based approaches try to regress these material maps directly, but since real ground-truth PBR data doesn’t exist, those models are trained only on synthetic interiors — …
