Vertical Biome Generation

[GenElectrovise]

In one of the early MC 1.15 (not 1.16 I think) snapshots, I heard mention that biomes can now be detected vertically, i.e. the biome at the top of a mountain can (in theory) be different to the biome at the bottom, and they would be stacked on top of each other. I believe this was in relation to the possibility of a mountain-biome update... I don't believe MC uses this at all as yet... (if it exists at all!)

Has anyone else heard anything about this?

 

Either way, I ask this in the context of me wanting to create underground biomes which are unrelated to the biomes on the surface. An example of this would be, perhaps, an underground "Evile Aquifier" biome for, e.g. a Kraken to live in. Another example would maybe be an underground fire biome as well; a floating islands biome as well -- again, unrelated to the biomes present on the surface. I would want them to each have their own custom generation -- no stone here! Only certified Evile-Blocks allowed!  

Would anyone have any suggestions on achieving this? 

 

Many thanks!

This is not a thing. Dinnerbone mentioned that it would be "a cool thing to have" six years ago. That's the most recent comment on it from anyone at Mojang.

Ok pretty conclusive...

 

How would you suggest I go about this then? Would it be something like world carvers? And for the sky "biome" a series of structures? (More of a sky archipelago than a biome, now  )

According to the minecraft wiki in snapshot 19w36a "Biome information now stores Y-coordinates, allowing biomes to be changed based on height. However, this is not yet implemented." 

 

It looks like horizontally divided biomes will eventually become a feature. As it stands, there might be a roundabout way of accessing the biome y coordinate with reflection, but that comes with a whole host of issues. Your best bet, until it's implemented completely, is going to be to use a sort of jigsaw structure generation.

Ah, thanks.

I'd done a google search (as the mojang website is a nightmare to try and search for information on) and hadn't even seen an announcement.

 

Anyway.

Chunk format

Biome information now is stored in sixty-four 4×4 arrays, allowing biomes to be changed based on height; previously, biome values corresponded to only the X and Z coordinates.

The  Biomes array in the  Level tag for each chunk now contains 1024 integers instead of 256. Each number in the array is the biome for a 4x4x4 volume in the chunk. These 4×4×4 volumes are arranged by Z, then X, then Y. That is, the first 4×4 values in the array are for the 16×16 chunk, at Y-levels 0–3, the next 4×4 is for Y-levels 4–7, etc.

There's some detail.

They'd probably better fix that

So it is possible.... Interesting!

Probably... I'll scout around a bit to see if there is a way, but otherwise, I agree!

Forge 1.16.1 32.0.7 just dropped and that *does* use vertical biome detection (visible in the nether from the vanilla F3 screen).

 

Doubt many people know much about this right now... Time to investigate...
