How do I import/fix fbx animations as ONE mesh?

I purchased a model from cgtrader for a game I am working on in the Blender Game Engine. The only formats available for the model are .obj and .fbx, but only the .fbx format has animations attached to it. The problem is that each animation has its own .fbx file with it’s own mesh (see picture below) and I need them to all be on one mesh, of course.

So my question is, how can I import all of these .fbx files onto one mesh, or is there a simple solution to transfer animations over from other models?

Any help is greatly appreciated. Thank you.


I solved this by importing all of the .fbx files into a separate .blend. Then I imported all of them as actions and copy and pasted the frames to the main action. It took a lot of trial and error, but I’m glad I figured it out.

I have a simlilar problem when using mixamo’s animation start from tpose, what is your .obj default pose?
