  • Isn’t colour data a vector of the r g and b?

    Yeah and since it’s basically a grayscale image with identical RGB values, the normal map ends up representing some weird surface with the normals being on a single line between (0,0,0) and (1,1,1). I guess the bump node finds the slope of the grayscale instead.

    I think in Eevee the Displacement node does the same thing behind the scenes, so having both displacement and Bump + Normal Map deriving from the same height data will probably double the effect.
