Stop Spectators Generating Chunks

Prevent spectator-mode players from loading new terrain

✅ Verified for Java 26.2 · Bedrock 26.32 — checked June 2026

Sets spectatorsGenerateChunks to false so players in spectator mode can only see already-loaded chunks instead of generating new ones as they fly. This keeps spectators from silently expanding the world and pre-generating terrain. Set it back to true to restore the default.

/gamerule spectatorsGenerateChunks false
