Adobe Air 3D
The most popular animated video creation software's which support both 2D & 3D, like Explaindio, are developed using Adobe Air. While Adobe Air is great and does support full 3D animations, the animation file format is very obscure.
The file format I am talking about is called ZF3D.
The problem is that there is negligible amount of 3D content available natively in that format outside of 3D assets provided directly by animation software vendors.
The only software, which does FBX to ZF3D.
