I would think that the bump should not change, at least it worked for me without changing the bump so far. And yes, I know that my script does not handle reflection and refraction

For V4 and other figures, I use VSS PR3 at the moment. Reflecting and refracting shaders are still things which I have to do by hand, that kind of stuff needs fine tuning, almost always. 

If you would put up a better script for sale I surely will buy it. Heck, I would pre-buy everything you put up, simply because I know which kind of quality I have to expect. 

Ice-boy, if I want it to be perfect, I will have to touch every shader. But since this is my hobby and my time is limited, I try to automate things as far as possible.And even if I fine-tune a shader, it helps to have the GC module automatically added to a material instead of plugging the nodes inside by hand. Especially in big scenes, with dozens of materials.
