Splet26. mar. 2024 · Linear roughness or perceptual roughness is the roughness value we assign when paint the PBR textures. However, it is intuitive to think that smoother surface is brighter (closer to white), so in Frostbite, we use smoothness instead of roughness. Thus, linear roughness or perceptual roughness equals to 1 - smoothness.
