The top tips for unwrapping roughness in 3D models are prioritizing clean UVs, hiding seams, and practicing with basics.
- Keep UVs free of overlaps or stretches—this prevents distorted roughness details. - Place seams in less visible areas (e.g., crevices, clothing edges) to avoid artifacts, and use tools like Substance Painter to bake high-poly roughness to low-poly models accurately. - Start with simple shapes (e.g., spheres) to master seam placement and consistency before tackling complex models.
