Phew, lighting works now.
/infdev/’s been updated with muuuuch faster lighting sky brightness recalculation than before, and actual working lights.
It also keeps a cyclic buffer of near chunks in memory, so it won’t run out of memory when you walk for a long distance. But since it doesn’t save anything to disk yet, you’ll loose stuff you walk away from.
Next up is working entities and working disk caching of chunks!
