I try to explain better.
After having prepared a 3D model, I usually import the model in Pepakura, a software dedicated to develop the planar surface of the model and to edit it in the best way. This is a common step in the paper modelling design process. The problem is that Pepakura recognize the geometry, of course, and the texture of the model, but it is not able to recognize the bumps and the other rendering components, that makes the model more interesting. The solution should be to have a texture (a simple .jpg file, for example) with all the rendering effects, of course fixed in a particular configuration, but this is not a problem...
As you see, the problem is linked to the conversion of the model from virtual to the real world...
sorry for not being technically precise, but 3DCG is not my precise field...
Thanks for your help.
Ciao,
