Map custom nether biomes to Nether Wastes when "above-bedrock-nether-building" is enabled #5972
Description
What feature do you want to see added?
I'd like Geyser to map any custom biomes (datapack biomes) to Nether Wastes when the "above-bedrock-nether-building" is enabled. This is because by default custom biomes get mapped to Ocean (ID 0) which breaks the nether fog and shows the overworld sky color instead.
Are there any alternatives?
Not exactly, but I implemented a hack solution in ClassTransform (basically a Mixin-like code injection library)
I don't have an actual PR-ready code for the Geyser project itself, but I basically injected extra code into BiomeTranslator#toNewBedrockBiome to use Nether Waste's biome ID when the session is currently in a nether-like dimension and the target biome is going to be mapped to 0.
