The Shader Doctor is a small utility to quickly correct some of the most common annoyances with the shaders on imported Poser Content. Just like the main importer, it is not going to be perfect – but it can get you to a more useable state a lot faster.
The main inspiration is sets like Stonemason, Nightshift3D, or Dreamlight: large sets which have hundreds or even thousands of shaders. They come in with pointless multiplication on the color channel, blown out highlights, and no (or unuseable) bump. The shaders on these sets often resist the “Consolidate Duplicate Shaders” command, and so to fix them by hand can easily take hours.
The default settings that the command chooses are reasonable for architecture: stone, wood, concrete. They are not so nice for skin or metals, and will not correct shaders that are supposed to glow.
