Get halfway through a model and find it's an unworkable mess? Can't add edge loops where you need them? Can't subdivide a mesh properly? If any of this sounds familiar check this course out.

Fresnel on specularity - which channel

Hi,

should it be applied to the eccentricity, roll-off or colour? If it's more than one of those, should the same ramp be used or not? I've googled this without any luck.

cheers

are you trying to get the specularity to be irregular, or to follow say a grain in wood for example?
If you are trying to do that then yeah you want to apply your map to spec colour.

if you want to adjust to spec roll off then apply your ramp to the roll off.

If you aren't sure what you are looking to do, then experiment and compare results from applying it to all three values on separate occasions.

Peace, love and Anarchy~~~~~~~
