Hello,

I've used Makehuman to create the body and imported it to blender to adjust a pose. From Blender you can export to obj file. Or you make a pose direct in MakeHuman and export directly to obj.For object files is an import written by Max Smirnov. You can find it here:

Maybe it's useful to reduce the size with a lower detail with MeshLab or something else.

Have a nice day
Karsten

p.s.: There is also a model made by Chipp Walters called Pat you can use: http://moi3d.com/forum/index.php?webtag=MOI&msg=7351.1
