I have a character model in blender and when I export it as an FBX and import it into Unreal, it imports 20 different files which are all glitched with 0 frames in length.
One of these files is the actual animation that I baked but the rest are just useless and it takes ages to import them all. What is happening???
It turns out this was actually an issue with Blender, while exporting the FBX, in the bake animation tab I had the “All Actions” option checked. Turning this off solved my problem, now I have one clean animation!
