The last item on the list: ************************************* When an .obj file which is referenced by a .pz3 is moved, the user has to locate the missing geometry file. The new path the user specified is now saved to the .pz3, removing the need for loacting the file on every subsequuent loading of the .pz3. ************************************* Please DO NOT implement this, it's bad practice for an application to change the contents of files during the loading process, as any problem or interruption to the application or system may end up corrupting previously good data. Loading actions should always be carried out in "read-only" mode. If the user wants to avoid the problems of reloading a moved object file (or for that matter texture files), then the simple option of resaving the pz3 should suffice without needing the introduction of a potentially corrupting mechanism.
