Hi,
Why is the texture map used in the 'color channel' affecting the reflection glossiness/roughness of a material? If I set the roughness of a 'Physical material' to be very matte, just using the slider and no textures for the roughness channel, then I'd expect the material to have the same overall roughness.. but it hasn't. See attached screenshot.
Not sure if I use the PBR material in the wrong way, but for example, if I'm rendering a product and I want it to have a printed artwork. I want the artwork to have the same surface finish everywhere (same roughness/glossiness), even if it has many different colors.. How should I achieve this using the 'Physical materials'? (I know how to do it using the Legacy Materials, but I want to try and use the PBR materials instead).
I use Cinema R21 and Corona "Version: 7.0 rc 5".
Any help is appreciated. Thanks!
