Finally figured out how to just paint on the glow, thanks to some help.
I think it looks brilliant. only issue with it is that the parts of her that dont glow arent able to be affected by light. so if shes standing in a blue room it will seem off, cause usually id make her arms shift toward blue aswell as nose and give the glow a slightly different colour. if anyone knows a solution thatd be great. my current one is to paint different version of the texture depending on the environment
