Many of you may already know this but... I was playing around with a concept that was tying Perlin scale to contrast with a common Slider. As the scale increased I wanted the Contrast to decrease so I'm thinking "I need negative values." Then I tried remapping the scale normally and remapped the contrast to Minimum:100 / Maximum:50. (Now purists may cry, that's not negative values, but Opposing / Inversely Proportional / whatever values. I'm just saying what I thought. smile:D ) The point is, I didn't know you could set the Min higher than the Max and have it function "backwards"! (If this is a bug, don't fix it!)

Every time you turn around, FF surprises you!

Have Fun (and hope this is new knowledge to someone...)

Palindromic modulation possibilities. I did it on purpose, not expecting it to work either, but I just figured run with it ha-ha. smile:D

Jim -- the contrast parameter in Perlin Noise is internally limited to positive contrast only. To get negative contrast, use the Brightness / Contrast component.

This is definitely not a bug -- we intended it to be this way smile:)
