I have a question regarding MeshPhysicalMaterial´s metalness and metalnessMap parameters.
If I set roughness to 0.0 and don´t use a roughnessMap + use an all white metalnessMap, I expect the material to be very metalic, but it seems metalnessMap is not causing any effect at all.
If I set roughness to 0.0 and don´t use a roughnessMap + use metalness = 1.0 and no metalnessMap, same material looks very metalic, like I want it to be.
Thing is, I do not want to use metalness/roughness per values but via metalnessMap/roughnessMap → but this approach seems to not take roughnessMap or metalnessMap in account…
I´m pretty goldfish of what I can do to fix or debug that
