Poser will find the textures corresponding to a MAT pose or a prop regardless of where you put the pz2/pp2 file (as long as it's in the pose or prop directory in your runtime, of course...) Same goes for textures, you can put them anywhere in the texture folder, Poser will find them and load them correctly when the MAT pose is applied or the prop is loaded. Don't ever move around the obj files in the geometry folder though, they have to be exactly where Poser expects them to be. The character file (cr2) has the exact path to the obj and if Poser does not find the file there, you're in trouble. You can of course open the corresponding cr2 in a text editor and edit the path to the obj file if you want to place the obj file somewhere else.
