Import .b3d into Blender/Unity | Convert .b3d into different format

I’m trying to import a .b3d model with its animations into either Blender, or straight to Unity.

I’ve looked all around, and there’s no .b3d importers for Blender. There’s one for Unity, but it’s pretty broken, and when I tried it. It barely worked.

I’ve also tried converting my .b3d model using an online converter, and a few other converters. But none of them seem to keep the model’s animations/rig intact.

If anyone of you modeling wizards wanna lend a hand, that’d be great.
