I have my resolution set at 4200px width and 3000px height.
I’ve set my aspect ration to x: 1.4, y: 1.0
However, the render comes out distorted.
For example a perfect circle is rendered (camera set to orthographic mode) with a width of 282 pixels and a height of 395.
Clearly there’s another setting which is over riding my render.
