Re: How to cut a circle in a polygon?

I basically made one hole inside a square using splines and extrusion. I used the Falloff shader in the Luminance channel to get the 'depth' pass. I used this render in the alpha and displacement channels to create the grid in the image.

This can also be achieved just using gradients too I think.
