I'm using Painter 3D to try to make some new textures, but although I know you can import a texture map, I don't know if it's possible to import images to use as bump maps, reflection maps, etc. Each preset has three "windows", the first with the colors/image and the third with black and white images to use for bump (and other) maps. When I import an image to use as a texture, the second and third windows are always blank. Does anyone know more and could you tell me? (I have Bryce 3D)
