Is there a simple way to mirror an animation and save it as a separate file?

Hey @DeCapital! Welcome to the Forums!

There is a built in function for mirroring animations in Unreal! Check out the Unreal docs on the subject here:

Mirroring Animation in Unreal Engine | Unreal Engine 5.0 Documentation.

I hope the above provides the solution you are looking for!
