Other users will probably have to put the obj in the same folder that yours is in, since Pro Pack wrote the CR2 to specifically look for the obj in that folder. But you can edit the CR2 with a text editor (WordPad, EditPad, etc.) and change the folder names so that it looks elsewhere. Another solution is to embed the .obj in the CR2 itself, so that it doesn't need to look anywhere. But I haven't learned how that's done yet.
