Note: support for BLEND 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://github.com/assimp/assimp/wiki/Cinema4D-&-Melange) IMporting geometry + node hierarchy are currently supported
