How to edit UVs for a mirrored effect on textures I have a hut model, here in blender from a game. I would like to export it to source engine.

It uses this texture below.

When I imported the model into blender, the textures didn't mirror like they do in the game I exported it from. They should look like this:

But when I export it, It actually looks like this in my editor:

It tried mirroring the texture itself in paint.net but that made it off center and look even worse.


My Only Option I guess is to manually edit the UVs So that it only covers the skull half of the texture. The other half is used for some other object in the level.
Can anyone show me how to do this? My UV editor looks like this below, when I select all the faces with that specific texture on.
For this, I dissolved the diagonal line going through the middle of my face. I then created a vertical loop cut down the centre of it, like so.

I then Went in the UV editor, selected all the edges of the left side of the face, and moved to be on the skull side of the texture.
All that's needed now is to download the UV: Magic UV Plugin, available in edit/preferences/add-ons, right click UV Unwrap Faces/Flip Rotate UV.
Done
