I wanted a low poly proxy with a mouth interior because I wanted to animate the mouth from inside a game engine (Unity) which has backface culling turned on by default, so I was getting this annoying hole out the back of their head whenever I opened their mouth. This mesh is "Male1591" from vanilla MakeHuman 1.2.0 Beta1, removed the tongue (why did it have a built-in tongue anyway?) and added a mouth interior. I made some slight adjustments to the lips to get it to export from MakeClothes2 properly. This is my first contribution to the MakeHuman community and I'm excited to have this opportunity! I love open source software and I intend to continue contributing whenever I have something of value to share.
