   Are there any skin optimizers out there?
  I'm currently tinkering around with vertex shaders and skinning and I've hit a problem that I'm sure people have already solved:Basically, say my vertex shader only has room for 30 bone matrices, but my model has 90 bones, then I need to break the model up into separate render chunks so each chunk uses a maximum of 30 bones (in this case the most optimized would be 3 separate chunks with each chunk using 30 bones each) Does anyone know of any public utils/source that solves this problem before I write my own? thanks-Steve.   
  The D3DX Mesh library can do this for you.   ;  And what about for OpenSource Libraries? there is a mesh optimizer for OpenGL?
