These are typically, normal, roughness, metallic, displacement and ambient occlusion maps. Images used to represent non-color data should not be transformed.The color space, encoding and whether the color values are proportional to scene-referred luminance or display-referred luminance also plays an important role. The correct way to interpret an image used as an input to a material channel depends on how the image is used in the scene. The purpose of this document is to detail the process of working with textures exported from Substance Painter and Substance Designer in 3D software and renderers. For more information, please take a look at the free PBR GUIDE VOLUME ONE on Substance Academy. Linear space rendering is a highly complex subject.
