Anyone know how to do a circular ramp inside cops?
When using ramp circular I get something reminiscent of the figure to the left, and what I'm looking for is the figure to the right. Your text to link here… [i1.wp.com]

A circular ramp like the one on the right is just a function of distance from the center point. Get the center by dividing W and H by two, then get the distance from the sampled XY position from that center point, then fit that to a range to determine your black and white points.
