Illuminate specific parts of a texture?


I have a texture with some “glowing” lights on it. I need those light parts to be illuminated but not the rest of the texture. Is there any way I can do this?


After some playing around I found an easy solution. Make one texture that is the full texture and then one with everything erased EXCEPT the pixels you want to be illuminated. Then get the Self-Illunim/Diffuse shader and in the first box assign the full texture and in the second one the illuminated pixels.
