Here's a comparison pic. It's a V4 double, both wearing the DAZ V4 Elite Lana texture. The one on the left is using VSS, and the one on the right using the DAZ Lana2_With_AO from the material room. Lighting is using one of muralist's EnvPanorama sets, the VirginiaDay preset, with AO turned off on the light, and both light intensities down to 50%.
