Wrongnether generation above Y:128 (custom world)Broken nether generation above Y:128 (custom world)
Brokennether generation above Y:128 (custom world)Incomplete nether generation above Y:128 (custom world)
Incomplete nether generation above Y:128 (custom world)Nether biome surface builder types incorrectly assume the world height is 128 blocks
if you use the new custom world generator to make the nether 256 blocks high there will only be netherrack, air and the bedrock roof above Y:128 with the exception for basalt pillars, lava and magma blocks in the basalt deltas an bone blocks in the soul sand balley.
this means that there are only nether trees, nylium, ore's, soul sand, soul soil, blackstone, sprouts, vines, fungus, fire, glowstone, gravel, a basalt floor and other blocks below Y:129 (in their corresponding biomes)This bug happens because the surface builder types for Nether biomes assume the world is 128 blocks tall.
Other surface builder types - which do not make this assumption - do not have this issue.
This applies to these surface builder types:
minecraft:nether_forest
minecraft:soul_sand_valley
minecraft:basalt_deltas
Likely it also applies to minecraft:nether, but I have not verified this personally.






the multiplayer sleep datapack from https://vanillatweaks.net/ sets the weather to rain for 1 second to reset the weather
the file i normaly use for the bug test is broken as of 20w49a
unfortunaly i can no longer test and update this bug report until i have a new file/datapack
i got a file that is working again
the bastalt deltas stop generating the ground above y127 so its just netherrack instead of blackstone or basalt
my current computer did not meet the minimum requirements and now snapshot 20w10a does no longer work for me and i will be unable to properly update the affected version on time
i think i can use another computer in the evening and continue updating this bug report.
also my computer is a lenovo T430 and only has intel HD graphics 3000 while the minimum requirements are intel HD graphics 4000
thanks for offering your help Michael but i already have another computer to test the snapshots on
@Peter Rabbit can i get that datapack, updating the .json file for the Import Settings button is a lot of work and my most recent version got lost when i got a new laptop
seems to be fixed, but biomes seem to generate 2D and not 3D
