Hey guys,
Turns out the banding was because of StepLarge after all:
Unfortunately I can’t abandon that because otherwise it takes tons of steps to reach the clouds. The remaining lines are due to issues with tiling the texture. However, I think this was the biggest hurdle.
Here’s my latest WIP. Before I start adding more details and shaping the clouds (and fixing the noise tiling) I want to get rid of the noise swimming seen at the end of the video. For some reason the noise “shifts” as I move through it. It’s most likely due to my large step size. Rays catch some noise at weird angles. However for whatever reason I can’t get the math right on “start from HeightMin, do large steps until you hit something, then step back and retrace path with small steps”.
