I'm trying to figure out how to apply these FBX's to my humanoid, rigged model in Unity.
When I import the FBX and toggle it open, it shows this: https://i.sstatic.net/VcIBu.png
and I can't hit Ctrl+D on any of those to Duplicate it into an *.anim (That's what a Google search recommended)
So, where am I going wrong? How do I apply these animations to my rigged humanoid character in Unity? I'm quite a noob, so please excuse me. Been Googling for a while...
Use Humanoid Retargeting.
You may have better luck using the BVH files from the website you linked and using a BVH importer here.
