how to make Half UV?

Musetatron

I have seen many texture maps that contain information only half of the model to save texture space.

Please teach me how to do to unwrap the half model UV.

I just found out that [cutting model in half > unwrap > mirror geo] works. Will this case a problem in the future? I suspected it is an overlapping uv?

thanks for pointing out that page. I have searched the wiki and only found lost pages.

Can I bother you to send me links to those broken pages? I would like to fix them.
