piexel 8a1c7ac998 Stop noise carving from stalling new worlds
Noise carving ran inside the cave carving pass, which visits every
chunk within cave range of the chunk being generated, and it looked up
the biome and height of every column in all of them. Opening a studio
froze the server for about 35 seconds on its first chunk, even for
packs that don't use noise carving.

It now has its own mantle component that runs last and only for the
chunk being generated, and it does nothing when no biome in the pack
uses it. A fresh studio's spawn chunk is ready in about 1.4 seconds
again.

Model used: Claude Opus 5.5
