Firstly, you will not be able to find data for every material you wish to recreate, so you need to use some logic to decide for yourself what values are appropriate. Additionally, linear space rendering means we no longer have to color specular maps the opposite color of our diffuse to get a neutral white highlight, while energy conservation in the microsurface function (rougher surfaces will have broader highlights with a dimmer appearance as the light is dissipated over a larger area) removes the need to manually make rough areas dark and glossy areas bright in the spec map. First, rename your texture layer in the Layers panel. Add a Comment. Let us make it more black and white to see the normal map effect on it.
