Ok it looks like the don't want to spawn in the Nether_Waste Biome what I origanlly had. If I spawn them in every biome the only spawn in the fungus biomes.. but thanks I finally got it 🤗

I see...it seems that the NetherVegetationFeature is tied to the vegetal biomes, what a surprise 🤔 ...there is another solution if you want your block to spawn also in the Nether Wastes, and thats to use the Decoration#UNDERGROUND_DECORATION (also VEGETATION is fine) stage and Feature#RANDOM_PATCH configured with a BlockClusterFeatureConfig. If you look into the NetherWastesBiome class you will see how mushrooms are generated there. Use a similar code to generate your bush adjusting the values you need. Your initial code for the BlockClusterFeatureConfig was not set up correctly and thats why it wasn't working. There is a function inside BlockClusterFeatureConfig.Builder which is func_227317_b_() which basically sets a boolean field (also not mapped for me) inside the class. I tested and it seems that you need to chain also that method to the Builder, otherwise your block won't show up. This should definitely solve your problems
