This is probably the most basic of mapping techniques...but I've never really given a map my all and tried to make things look good, and now that I'm trying, I'm having problems with texture stretching while making triangular rooftops.

I'm simply using vertex manip to create two right angled brushes to form the roof..however all but 2 sides are stretched. Is there another technique to making these rooftops or is there a way to fix the stretching?

make sure in the texture box the face box is ticked (I think it's that one, it will stop the stretching)
