I don't render in Poser but in Carrara. I use Poser a lot, though, for dynamic cloth and the walk designer. I noticed one thing: I never see poke through after running a simulation with V4, but there's lots of poke-through with M4. I would like to use Trekkie Girl's clothes for M4, but it's practically worthless. Is this because V4 is designed differently than M4? And is there a workaround   that  problem?
