Mesh and Skeleton (4.27)

Hi, first post here.
Currently im thinking about how to animate the unreal Third Person Shooter model.
Basically, what I was thinking about doing is to take the model&skeleton, get it to blender, and animate it from there, then, export the animation to UE, after all that, i would just attach a mesh to the skeleton that i had animated (first, would be just the current UE white robot).

The problem that im having is, I cannot seem to find i way to export the skeleton&mesh into one fbx, that from there i would be able to animate it, any ideas abt how to do the export right ?

Thanks!

Look for the SK_Mannequin, right click, then Asset export > Export > make sure to select “Export preview mesh” and then try to import the FBX into Blender, it should import both mesh and skeleton.
