PZ3's, texture files and non-poser ready models can go anywhere.

CR2's need to go go in one of the subdirectories under RuntimeLibrariescharacter.

PP2's need to go go in one of the subdirectories under RuntimeLibrariesProps.

HR2's need to go go in one of the subdirectories under RuntimeLibrariesHair.

PZ2's need to go go in one of the subdirectories under RuntimeLibrariesPose.

OBJ files that are required to load PZ3's,CR2's, PP2's and HR2's generally need to go in a specific directory under RuntimeGeometries. You can open up the Poser file in a text editor and one of the first lines will state where it pulls the OBJ from...thats where you need to put it.

Hope this helps.
