      every time you make a world 90% of the time it uses the surface biome leading to blank caves

      this is easier to show in a custom world with fewer biomes like two surface biomes or cave biomes I think it’s a bug 

      I will upload a datapack I made that does this 3D biomes bleed 

      It does it on the normal world that’s how I found it and started using datapack worlds to test 3D noise

      got no picture yet

      watch this YouTube vid it shows what I mean https://m.youtube.com/watch?v=Y35JVgDvLFQ 

      when you add two or more biome layer cave biome also bleed to the surface it happens with just two biomes but its less noticeable 

      i have added a datapack look for cave biomes and go up top and watch the vid for underground

      my biomes are set up 3d so whats happing is not intended note with the pack biome are large so render my not show it on spawn

      the desert is meant to be the only biome for the surface

      found if i use -2 to 0 and then 0 to 2 for the two biomes it works as intended i think its for values in between the preset values
