[Unfold 3D] Straighten edges

Filip5

Hey guys, I got somewhat stuck unfolding the very basic shape, altough, I can't get the edges straight...



This part is being bend over here. I also had to adjust the smaller U shape above. But this one just won't bend over, lines are not being straightened properly and overally this shape just acts wierd. I wonder if anyone knows how can I straighten this so my textures will display properly on this...

I'm not sure if this applies to Unfold 3d if it's no in Maya but check this video out.
