Great!

FYI: What I meant when I said "stepped" ramp, isn't the correct term for what I meant

A stepped ramp is a ramp that is striped like stripes on a shirt, I believe.
It normally goes from one color, then step's to the next color with a little, if any gradient color shift.

The ramp I was talking about was a simple ramp that goes from white to black with NO gradient. So, just a hard white, then a hard black, like a checkerboard

Good luck!
