I'm trying to UV export a very simple rectangle so that I can import it in Photoshop to paint my rectangle. I need to do this because my game engine requires both the naked model file and texture file.
The problem is that whenever I try to unwrap the rectangle I get the unwrapped image on the left .. which shows the faces as squares instead of rectangles. This makes painting REALLY hard since I'm painting in a square (1:1 ratio) which gets translated to a rectangle.
My question is: How do I unwrap my rectangular model in a way that the UV map shows the result in rectangles instead of squares?
