Rhino with FBX and or gITF?

I’m looking for a a Iguana 3d model for a project. The one that I found so far were only available in FBX and gITF formats. I don’t know what gITF is , but Rhino doesen’t seem to open or import either. Any info on why?

Got Google?

Supported File Formats

MotionBuilder .fbx 1 1

Thanks for your detailed an nuanced response. I love this forum, and it’s responses like yours that keep me coming back.

For other noobs, my mistake re .fbx was that I was expecting to find it in the file import list after the E formats. Someone pointed out that .fbx is the MotionBuilder format and found under M.

Just sayin’; try a search!
