I have recently found out of a tool that I was looking for for very long:
U3D (which I really hope I can distribute here, since I don't want to do anything other than good). I'm sure many of you were also looking for a way to convert .obj animations exported from Blender into .3d files for Unreal! So, why not rejoice?
I only want to help, so please don't think I'm posting this for some bad reason. If you already know about the tool, or if I misunderstood something, please let me know.
