I'm trying to make a material that steps the surface illumination of the object from 0 to 1 in <x> steps (32 in this particular case.) Can anyone give me some ideas about how to go about it? I still don't really totally understand what all the inputs I have to work with. I think "map coords" will be a number between 0 and 1 over the x,y,z of the material as it is mapped to the object, no?


Hi Matthew,

See the attached image for a VSL material that will do the business.

Thanks Richard! I did manage to work it out last night (took me about 2.5 hours), just before you sent your material... However, your method is 3 operations shorter than mine, and I love learning better ways to do things. I did change the level from "Surface Illumination" to "Surface Properties" though. Not sure how that plays into the overall rendering pipeline, but I like the results better. With Surface Illumination the color of the object would seem to go to black, or near black. But with illumination at 0, the color of the object should just be the normal color of the object. Also, I added a curve to control the upper and lower limits of the overall illumination. Oh, I also learned about the Material Initialization level, I didn't know that existed. It worked out very nicely, thanks again!
