Is this possibly related to the geometry .rsr file? Colm, has it created an .rsr for the .obj when you first tried loading it, and if so have you tried deleting the .rsr? I've been making a few custom conforming figures lately that I've tested extensively in P4 and PP and haven't run across this bug. Hope this helps. Oh and FYI, Scott, when I reported the Spherical fall-off zone bug to CL it turned out they already knew about it and were testing the fix for it in SR2 at that time. That bug was introduced with SR1 and fixed with SR2.
