Sodium/Rubidium Occlusion Culling Fix Mod patches an invisible chunk bug in Sodium and Rubidium. The base game solved this missing world problem a while ago, but those two mods accidentally brought it back. This patch makes sure your world loads correctly without any blank spaces. It might drop your frame rate a little bit, so you only need to use it if you actually see broken terrain.

Features:
- The Sodium/Rubidium Occlusion Culling Fix Mod solves a specific bug that makes chunks of the world turn invisible.
- Forces the game to load and show blocks correctly so you do not see random empty holes in the ground.
- Clears up visual errors across large landscapes, keeping mountains, forests, and caves looking normal.
- Works directly alongside your active Sodium or Rubidium setup to correct how the game hides unseen blocks.
- This mod might drop your frame rate just a tiny bit, as it takes extra work to make sure every visible block stays on your screen.
