I try to UV map the standard cube created when starting Blender (v2.79).
I'm following a tutorial (https://www.youtube.com/watch?v=vbj4d5XL0NA), using Cycles and have made these seams.
The cube size is standard 2x2x2 but move a little in Z-direction.
When I try to UV map it I get the following result.
Why do I get rectangles instead of squares? Is there some way to easily change it to squares?
This is the settings of the cube
