Can this issue be reopened? The issue that this was duplicating was resolved as invalid for some reason.
If that's the case then the player shouldn't also be able to spawn in deserts, badlands or most other biomes except for plains and forests
Actually, the E value stands for erosion, which controls how flat the terrain is, which means that mountainous biomes like the stony peaks generate when erosion is low, while swamps only generate when erosion is very high, so that they can always be near sea level. Also, deserts are more likely generate in areas with high erosion, and can't generate near mountains, as these get replaced by badlands instead of stony peaks.
Can confirm for 21w44a
Can confirm in 21w44a
This issue still affects 1.17.1 and 21w43a
Can confirm in 21w43a
Can confirm in 1.18 Pre-release 7. The solution for this should be simple, just change the temperature value in the biome file to 0.9 or 1.0 so it has a more vibrant and lush grass color
