Flip character mesh

I have a 3D character on a plane and I’m rotating it by 180 degrees to have it upside down:

But the character of course is not facing the same direction.
This is what I would like to achieve:

Is there a way to flip/mirror the character mesh?
I tried to use the only way I could find around, multiplying the scale of the desired axis by -1, but I get an inside out mesh instead.
Or if there is any other type of rotation I’m not aware of that could also make me achieve the same result.

What is flip/mirror actually? This is just rotation by one axis, nothing more. If you want to use -1 scale you need to set pivot of your mesh to flor, see unreal character example. If you sen -1 scale on it you can get a mirror. But you can just rotate mesh too (use Pitch).

yes, if you rotate 180 degrees on a different axis, you’ll roll the character over to be upside down and he’ll still face forward.
