After normalizing the values to a 0-100 range, I get this curve on the perlin/classic2D.
On the left are the ranges, as in 0_9 is from 0 to 9, and on the right the percentage.
But I suck at math, so what do I have to learn to make this curve more linear, meaning I want to make values equally proportional across the board, "flatten the curve" I guess, e.g. like 10% per range.
EDIT: I did some research and I guess this is a bell curve, or a gaussian, but when researching "how to flatten a bell curve formula" I had no success.
