that's what i figured. what i failed to use was a vec4 to vec node. i now believe i have it working.

hello all. I was just wondering if there was any way mask a bsdf from another with a texture/alpha to get a layered type of shader. one layer highly reflective and a second one blurry for example. Is this possible at all? I'm kind of stumped. lol. thanks in advance.

Just made an implementation of this paper. GGX specular is so cool!

GGX, how I love you. Great work.
