So, a Meshinstance wants to have the mesh as a constructor parameter, but CompileNewFunc doesn't seem to get enough information to get it from the C4Object that is being compiled. We could duplicate the StdPtrAdapt to make it pass through an additional parameter to the constructor, open-code the necessary bits in C4Object::CompileFunc, duplicate the information in the serialized MeshInstance, or replace the Mesh reference in the Meshinstance with a Mesh pointer. None of this strikes me as particularly elegant, but I can't think of a better solution. Am I simply too tired?
