Originally posted by BennyK have photoshop, and i know the difference between lambert and blin, phong and phong E (I don't know the difference between the later three... Can someone explain that?). that made me smile. basically a blinn and phong have specularity attributes that you can adjust. i think phong shaders are more realistic but take longer to compute. for photoshop you're just going to need to start experimenting. look up a few basic tuts to get a feel of the tools. focus on the color map first - get that right and then can use it for painting your bump and spec maps. try to think about where an object is shiny or not for the spec map. that adds a lot of realism. here's a good overall tutorial of the process. https://www.leighvanderbyl.com/tutorials.html as for your bump, you need to lower the depth on the bump2dnode. pretty low - like o.1.
