- Unfortunately aiNode has bone structures and meshes too, yet we can't assign
- the mesh to a bone aiNode as a skin may refer to several aiNodes. Therefore
- I've decided to import into this structure:
-
- aiScene->mRootNode
- | |->mMeshes (all the meshes)
- | \->children (empty if there's no skeleton imported, no meshes)
- | \->skeleton root aiNode*
- | |->bone aiNode
- | | \->subbone aiNode
- | |->bone aiNode
- | | ...
- | \->bone aiNode
- \->mMeshes[]
- \->aiBone, referencing mesh-less aiNodes from above
-
- * - normally one, but if a model has several skeleton roots, then all of them
- are listed in aiScene->mRootNode->children, but all without meshes
