Alternative for GeometryBatchFactory?

Is there an alternative for GeometryBatchFactory to where I can edit individual blocks without having to reload the whole thing every time a block is edited?

You mean a MinecraftWorldFactory?

There is no such thing.

This is a common pitfall to start to make a Minecraft clone by stacking cubes.

Minecraft is not based on stacking cubes, it’s based on mesh editing.

When you “add/remove a cube” you have to edit the underlying mesh.

This can help
