The scene tryonmaster, might be worth looking at. I still have to add a few plugins to add to the experience. I add about 15+ additional plugins. Any way, add Alive plugin and learn how to use it. I think the scene comes with VAMMoan, learn how to use it, turn up to 4. SXS4 has some simple animation sex scenes with 50+ positions, but the same thing applies, learn those two plugins to start . There are tons of great plugins. Its worth the invested time to learn the basics. I think I know what you mean by skin physics. There are mouth, breast, glute, genital physics. It would be nice if any where you touched the skin there was a little physics, like on the face cheek or thigh or feet. It would be nice. Not sure if my PC could handle it though. The plugins are the key, even a simple scene with the person just standing there, can be made to appear alive to some extent with plugins. I am not even close to understanding this stuff, but at least with some plugins, I get some pretty good results.
