I modeled an anti-tank barrier for a HalfLife2 mod and then skinned it photoshop. It was a big step forward for me in terms of uving and then getting it all working and a working skinned material on the object but I see I have a lot of texture stretching.

Where did this occur do you think, in the uv when I was sewing edges or what?

what is the first thing that pops into your mind?
