VRayBump2Glossiness utility texture generates a reflection glossiness texture from a bump or a normal map. Use of this texture avoids the effect of overly shiny or too highlighted glossy parts of objects seen at a distance. With a reflection glossiness texture generated from bump/normal map, proper reflection glossiness is achieved at any distance, while detail is preserved.
To achieve that, VRayBump2Glossiness takes a bump/normal map and mixes it with a (separate) reflection glossiness map or value, and the result output is fed to the shader.
Note that the Bump2Glossiness output is always reflection glossiness.
