I've also uploaded a stand-alone demo of Nogredex, you can get it here
I've removed the 16 bit index limitation on meshes. You should now be able to load any size mesh you want. (I wouldn't recommend it tho, in my testing I found that Novodex starts to bog down on meshes larger than 10,000 triangles).
Meshes with more than one sub-mesh are now fully supported and correctly simulated. I've also added some optional code that will even optimize these types of meshes by removing duplicate vertices.
