Are animations exportable with fbx files?

Should I export them separately?

Can I import them with assimp if I import them in either ways?

Thanks

Are animations exportable with fbx files?

Yes. When exporting the skinned mesh you will often export all the animations with it.

Should I export them separately?

The common workflow is to first export the skinned mesh with the bones, with no animations. Then using your software break your animation into actions ,Idle_Look,Idle_Scratch,Walk, etc.

Depending on your exporter you will either be able to export each of these as a animation .fbx, or you will have a animation file that when imported will create separate animation actions in the new software.

There are no hard rules, use what works for you.

Can I import them with assimp if I import them in either ways?

No idea, I don't use assimp.

It's important to know that most exporters will change the "Bones" of a .fbx file, it still work it just looks strange when you import it back.
