This hugely popular addon for the UV Editor reshapes UV selections into a grid. It respects vertical and horizontal face ratios and can stretch out any selection shape.

No more manual alignment of a distorted UV Blender’s UV unwrap is far from perfect. Quite often, you end up with a distorted shape of your object and have to clean it up. This takes time and effort as you select all the vertices and re-align them via the appropriate axis, repeating this endlessly. What if you could do it with a single button push? That is what UV Squares is all about.

How does it work? The process is simple and quick. Once you have unwrapped your object, the UV Square addon will turn your UV into a perfect, clean shape, respecting the geometry of your object. The distortion is gone and you are good to go!
