"... Ok, I guess maybe what you are saying is that you don't want to decide anything at all about visual appearance or materials (other than that some objects that are mirrored from one another should have equal appearance) until you're actually totally finished with the modeling and you don't want to even start to think about the final materials until you are in your rendering program and done with MoI, is that it?"

Yes Michael exactly!
Thats why I say about 300 styles becouse I want to have absolute freedom coloring model in render soft. I'm not that person that now in advance how the model will look. For example with this spider I have one idea how to color it but when I started to color I understood that it look bad. And I started to look for another color gamma and how to color another objects. Unfortunatley in moi I can not deside wich color I will use and on wich object.
