Another thing I've spent a while trying to figure out, searching for, but alas no solutions exist online.
So I thought up the logical and actually quite simple answer to this problem:
Biome variations.
Since the cave update, Minecraft handles biomes in 3D. However, MCreator only allows for 2D biome generation in any dimension apart from the Overworld. But you can get around this limitation by making a copy of your biome, perhaps making small changes to its generation, and using features to replace the natural stone in that copied biome much like how you would with custom stone layers. By doing this, you can clearly define the Y Levels you want this mock cave biome to generate, and it will be restricted to only generating within the copied biome you have made.
It's not a perfect solution, but it is the best you can get with MCreator's current capabilities.
The biggest flaw with this method is the potential for chunk loading lag, but from my testing it doesn't appear to be anything major. And I have quite a lowend PC.
- Create biome.
- Copy biome.
- Create feature to replace copied biome's natural stone at certain Y Levels.
- Allow both biomes to generate within your custom dimension.
- Cave "biome" now generates within the copied biome. Original "root" biome remains untouched.
- Congratulations, you've done what seemingly no one on this site has ever thought of before!! (..until now i guess)
