Other noise-based terrain generation features to try breaking

[muzikbike]

I personally haven't been able to break these myself, but they could yield some potentially interesting results:

• Biome generation: these (at least in 1.16+, according to this video https://youtu.be/VYZl2MUat-M) use several stacked layers of Perlin noise to define where they generate. As is stated in the video, there's no way in vanilla data packs to customize the scale of this noise so modding to scale or offset this is more than likely required. Phoenix Terrain Mod seems to use simplex noise for controlling biomes, and overflowing with this results in a diagonal zigzag leading into a plain forest.
• Swamp noise: Controls the marshy areas of land in swamp biomes. The temperature in swamps is also gradually varied on the client side (which becomes obvious in a flat swamp world) using this noise at a different rate, which gives the grass its two distinct colors. Breaking this would likely result in the color distribution becoming stripes instead (best seen with no biome blending).
• Badlands biomes: CubicWorldGen lists two distinct noise generators used for mesa generation, namely "mesa noise pillar" and "mesa clay band offset noise". I haven't tried breaking these and am not sure what results each would yield.
• Flower distribution: Upon world generation (post-generation using bone meal is different and from what I remember is not seed-dependent) perlin noise is used for placing flowers in different groups within flower forest biomes. Breaking this might give way to some interesting patterns. I'm not sure if plains use the same trick for tulip areas.

I have made a mod on 1.12 that allows scaling most of these features. Flower forests will generate only red tulips after around 60 billion blocks on one axis (with a diagonal line marking the boundary). In badlands biomes, the clay bands will simply no longer be offset after a certain distance (somewhere before 1 trillion blocks). The pillar noise is used for generating Mesa Bryce biomes, and I haven't tried breaking it yet.

I'd be quite interested in seeing screenshots (as well as possibly a mod download at some point in the future).

After inspecting the code, it seems that all of these use simplex noise, which only generates a certain "middle" value after it overflows. Swamplands would simply not generate these marsh-like areas, and would have only one grass color after a certain distance. The badlands noise generators overflowing would not be very exciting either.
