Ambient Occlusion ( Blue) Īmbient occlusion maps are a baked approximation of shadows. The changes in both the size and brightness of the specular highlight. Compare roughness values of 0.0, 0.25, 0.5, and 1.0 in the demo above to see That are much darker than a glossy screen. A rough, matte screen, for example, has reflections Highlight darker to preserve the overall amount of light being reflected.

Physically based surfaces shouldn't reflect more light than they receive, so larger roughness values make the specular In the demo above, set metalness to 1.0 and experiment with different Resulting in more even specular lighting. Higher roughness values use smaller mipmaps, This is achieved using a cube map and mipmapping. The environment reflections will look blurrier for larger roughness values for both metals and non metals. Rougher surfaces have larger specular highlights than glossy Roughness affects the size of the specular highlight. Skin materials are a special case and instead use the metalness map as a mask for the fake subsurface scattering effect. In the demo above, note how the specular highlight becomesĬloser in color to the albedo color as metalness increases. Metals have no diffuse componentĪnd specular intensity is controlled entirely by albedo.

The specular intensity for non metals is controlled by the PRM's specular. Non metals have a white specular color and the diffuse component is colored by the albedo. Values in between 0.0 and 1.0 enable smoother blending between metallic and non metallic regions of a model. In general, materials should be either fully metallic (1.0) or non metallic (0.0). Metalness determines whether a surface is metallic or not and affects both specular and diffuse shading. Maps to raw, non color data, or linear to ensure When rendering in programs such as Maya or Blender, set the PRM sRGB formats have names that end in _SRGB.
