I finally nailed the smooth rotation of a noise field. No unsteady or flickering edges anymore. No quality loss no matter what the actual rotation angle is.
Wow you have been playing with noise for a while :) . It amazes me all the different noises that exist now.. Perlin, Simplex, OpenSimplex, OpenSimplex2S, OpenSimplex2F, Worley... If you are curious about OpenSimplex https://github.com/KdotJPG/OpenSimplex2

Some of the results of my work-in-progress tool to generate random tile-based worlds. (More info in comments)
Probably true, although a neat repo for open simplex is https://github.com/KdotJPG/OpenSimplex2

Value Noise Resources
This may not answer what you're actually looking for - but a few years ago I found a library for coherent noise in Java, which at least meets my needs. I use bits and pieces of the Open Simplex Noise implementation from that library. It's unlicense/CC0, so easily copy-paste-able straight in to one's own project. https://github.com/KdotJPG/OpenSimplex2/

Question about OpenSimplex2S
So I was looking for a noise function, and I found this repo from the author of the OpenSimplex algorithm. And in the GLSL implementation, which is the one I'm gonna use, since I want to generate terrain with compute shaders, the function%20%7B) looks like this:

How would you loop a 3D noise?
If you want to feel safer from that, you might opt to use one of these instead. Use the ImproveXY endpoint to get a Z that repeats after 500.5626833874055. Go up one directory and into the glsl directory if you need GLSL versions instead .

Map + River generation using the "Lanczos Value-Noise" I wrote [Details in the comments]
Fair. I definitely agree Simplex has some characteristics that don't work great in some places. Especially when you threshold near zero of a single octave. Have you tried OpenSimplex2S? It's made to be less "bubbly" than standard simplex. In own repo, In FastNoiseLite, [Shader preview (3D noise)[https://www.shadertoy.com/view/ttdGR8]. Both the 2D function and 2D slices of the 3D function might be worth looking into if you haven't yet.

Need some help making the GLSL implementation of OpenSimplex2 tileable
Here's a link to the original implementation: github.com/KdotJPG/OpenSimplex2/blob/master/glsl/OpenSimplex2.glsl
