its pretty easy to pull the geomitry out. and fix that. not sure what your p5 commands are going to do in p4 . I dont have enough memory to open poser up yet to check. Theres allot of node this and node that stuff in the pp2 file. You can probley just whack that part out for a p4 version. Cant say for sure never tried to open a P5 prop in p4 before.
