Simplifying mesh using hkQemMeshSimplifier

Hi.

I've been playing with havok since recently and have a question I'd like to ask.

I need to simplify a mesh to use with hkpExtendedMeshShape.

Is there a way to convert an ID3DXMesh mesh to hkQemMutableMesh, so I can simplify it using hkQemMeshSimplifier?

Thanks in advance.
