So the story goes on. Ive done (as accurate as possible) as SamTherapy told before.

Saved the amplifier as a character as well as a prop. But there is no obj. file or path mentioned in any of the .cr2 or .pp2 or .pz3 files nor saved in any folder in the Runtime section. The entire structure of the object is stored within these files. I`ll never understand the complicate file / folder / library structures of poser or daz... Found the texture paths are written in an absolute way when I open the mentioned files in wordpad. Can I change it to a relative path, so i can move my directories ?

Being nearly finished with my objects, i now unfortunately need to do little corrections in the main structure of those models. But how, when there is no more an obj to change ?
