Yo! calling out to all my VFX peeps! I am trying to get an SSS shader to work with a highly reflective material in Mental Ray to make a bronze or copper material with it. The closest I have gotten is using the Mila material but for some reason the Mila material doesn't want to work with an image node to mask out the areas I do not want the shiny material to show. It only works with default nodes like checker or fractal for some reason. Any advice would be appreciated. I already tried the color mixer and the fast SSS fast skin shader but then I lose the scatter. This also only works with non file nodes also. I think it has to do with light linking. Thanks!
Have you tried connecting the Out color R of your mask texture to transparency instead of dragging and dropping?
