I want to do a scene of a primitive figure rapid in  skin robes.

Any seen around or ideas how to use standard props in P4 to get a good results.

For a lady you can use the a transmap with either P4 thinstrap dress or the catsuit.  For a gent it gets a little more tricky, I ran into that problem when creating Gilgamesh and ended up using one of Judy's dynamic skirts fit to him by using the cloth simulator.  What version of Poser do you have?  With conforming clothing it may be more tricky getting one of her skirts to fit him properly.

Old P4... P5 crashes on me.

OK, then dynamic cloth is not an option.

Will you be using any male characters in the scene?  If so would a loin cloth be appropriate?  There are some around for M3 and perhaps can be scaled to other gents.  Also perhaps, the P4 T-Shirt could be scaled to be longer and then with a transmaps it might get that cave man cut.
