Selecting parts of mesh for UV with mirror modifier? I'm trying to get a uv map for this shirt by selecting it (it uses EA's template for Sims 4). I have the mirror modifier on and I can't seem to select these parts. They also don't show up selected in the UV (modifier doesn't apply to it). How can I select these parts?
You can select those parts if you apply the modifier in object mode as shown below:



If you need the modifier and want to keep it, whatever you do in the UV Editor will be mirrored.
