The pants are a subdividing mat that comes with Bishoen from Daz. There's also some free subdividing mats here in freestuff. It assigns different materials to various body parts so you can texture them seperatly. V3 looks as though it was sesigned with this in mind. Mike 2 and Vicky 2 have a few jaggies where some body parts come together, so you don't get a perfect seam (hip to abs and neck to chest). The lines on V3 are very smooth.
