I have an .fbx file containing a an avatar that is standing still.

I followed the steps in this GitHub repository section “Motion Generation” to create an animation for that avatar. What I received were an .mp4 file and a .npy file which contain the movement that I want the avatar to do.

Is there any way to connect between them so that the avatar will move like in these files? The animations are going to be applied to many different .fbx files.

I am sort of looking for something like Mixamo, but with a way of importing an animation and not only an avatar.

Try using their Avatar2FBX tool. Just before the section on Motion Generation, they have this section:

Convert Avatar to FBX Format:
For the convenience of using the generated avatar with modern graphics
pipeline, we also provide scripts to rig the avatar and convert to FBX
format. See the instructions here.

However I’m a bit skeptical will do everything you need as that page lists animation as TODO & near the bottom it notes:

we currently only supports ‘stand pose’ and ‘zero beta’

Their Avatar2FBX tool appears to be based on other work. If their ‘bundled’ version doesn’t work, you could try looking for a more active or original source with the hopes that it has the functionality you’re looking for.
