I got a bit of conundrum here. Arnold (in Maya) and specular roughness. If I input numerical values into it, I get completely different effects compared to if I input a texture (See the photo attached). The funny/weird thing, is that no matter what texture I input into spec roughness (pure black, pure white, a proper detailed texture etc., anything actually!), I get the exact same look no matter what. What is going on?
Surely a greyscale texture is nothing more than a set of numerical values, and as such it should be able to generate the same effect as if you had put that numerical value in procedurally/with numbers/sliders. Why not?
It is puzzling/frustrating me no end. I hope some of you know the answer!
