Horizontally flipping PlayerModel object

[Eungavi]

Hi fellow forum members!

I guess title says pretty much all.
Currently trying to flip a PlayerModel object horizontally, but nothing worked out for me. Unlike 3D model, 2D portraits were super easy to flip as you just need to call :SetTexCoord(1, 0, 0, 1). However, 3D model doesn't seem to work this way as frame widgets don't have SetTexCoord function
(SetRotation didn't do a trick as well...)

Any ideas, please?
