Note: support for [BLEND](https://en.wikipedia.org/wiki/.blend_(file_format)) is deprecated.
It is too time-consuming to maintain an undocumented format which contains so much more than we need.

Additionally, some formats are supported by dependency on non-free code or external SDKs (not built by default):

- [C4D](https://en.wikipedia.org/wiki/Cinema_4D) (https://github.com/assimp/assimp/wiki/Cinema4D-&-Melange) IMporting geometry + node hierarchy are currently supported
