I realize this might seem a little like some other posts I have read, but I have a slightly different problem. I painted a model and tried a test render. Only some of the colors showed up. A near black one appears to be brighter than a skin colored one. all of the colors are in the same image. I think I have unwrapped everything correctly, as some of the colors show up. Basically, some colors are showing very bright, and others as black. I read somewhere that this might have something to do with the smooth shading and subdivision surface, but I disabled smooth shading and nothing changed. I tried adding the filmic log base encoder but the same result occurred.
Thanks for your help
