[solved] OpenSimplex Noise producing extremely noisy results

Newbie & Debugging Questions
#1

I recently came across OpenSimplex noise which looked like exactly what I wanted for some small procedurally generated game I’m making. However when I wrote the noise to a file (128x128 - the size of the world for now), it looked really… noisy, which reflected back into the terrain generation.

The colour is calculated as ((noise + 1) / 2) (I’m assuming the noise is in a range from -1 to 1). I am using the 2D method for noise.

The simplex noise implementation I’m using: https://gist.github.com/KdotJPG/b1270127455a94ac5d19

Lower the frequency.

eval(x * f, y * f) where f the frequency. If it was 1, then there’s your problem.

Holy crap that was so much better!

(0.25 freq.)

Thank you! ;D
