Need some color math



  • I am creating a 2nd skin suit for Sydney G2. I posted some renders in the Superfly thread, but I want to create a mask to cover her face:

    I know how to create the mask for the specular highlights and keep them from affecting her face, but how do I create a mask so I can add a bump map to the mask and keep that from affecting her face. I don't need an 80 node solution, just something simple.
    Thank you!



  • Never mind. I figured it out. I added some displacement too...

    @rokketman Use a mask -"mask", in the sense of a discriminatory B/W image map- to define where the face mask should be.
    Gamma should be set to 1 for the B/W discriminator mask image.

    Use a math functions node (set to multiply), and multiply bump times discriminator.

    If you want both skin bump and facemask bump, use a blender (blending set to 1).

  • Yeah, cousin, I am getting better and better at this stuff. Mostly because of your help. And, of course, BB and trial and error.
