Prove concept : LeiFan Transformation cut fat panty 1.0.0

This is a proof of concept work on cutting clothes by turning them into transparent. I was planning to turn Leifan into stocking, but having a bit mesh conflict problem, so just show legs instead. There is a weight miss-match between the brief and the leg, so there will be a gap in some postures. I don't think I will fix it though, because this model don't have body dynamic for legs, many of you guys are not happy with cannot-bouncing legs anyway. I will look for another model later.
