I know this seems like a dumb question but someone told me the only dumb question is the one not asked so ill throw this out and hope you guys dont flame me for posting it. I used the brush tool and created a square. I made sure it was nodraw texture when I created it. My problem is I cannot pick just one side of it to texture, I read keeping all other sides nodraw will improve performance but I dont know what to do to select only one side. I tried CTRL U and even tried clicking in various tools, could someone help please?
