hollow-cube/lighting-memory-reduction
Lighting reduce memory + Fix lighting not sending + Performance (#31) * Reduce memory * Clone * Executor pool + cleanup * Cleanup * Don't batch, it's slower * Parallel chunk loading for test * Check below chunk 6. Sky light data doesn't appear to be saved above the highest point in the chunk height map. * Fix weird locking * ඞ * Fix test * Fix indentation * Use short instead of int * Use short instead of int * Start removing borders * Borders gone * Cleanup * Cleanup * Remove borders fully - Still needs cleanup * Cleanup 1 * Cleanup 2 * Cleanup 3 * Cleanup 4 * Cache * Performance * Performance * Cleanup * Cleanup * Refactor * Cleanup from self-review
