Sodium/Rubidium Occlusion Culling Fix
by yezhiyi9670
Sodium/Rubidium Occlusion Culling Fix stops chunks that should render from disappearing, by restoring the MC-70850 workaround that Sodium and Rubidium had brought back in Minecraft 1.18 and later.
What it does
In Minecraft 1.18 and later, Sodium and Rubidium reintroduced a problem where chunks with visible letters or blocks could be hidden by vanilla occlusion culling, a bug tracked as MC-70850. This mod disables the affected occlusion culling path so those chunks stay visible. Mojang had already resolved the underlying issue, and Sodium fixed it officially in 0.5.0, so the mod is only needed on the versions where the bug returns.
The fix is a near-proper workaround, but it does not match the intent of the original code exactly, and it can cost a small amount of performance. Players who notice large frame-rate drops should remove the mod before blaming Sodium, since it is one of the possible causes. A related issue, MC-63020, produces similar symptoms and has been addressed in the same way. The mod was backported to the versions that still need it.
The mod requires both Rubidium and Sodium, and the issue exists only with one of them in use. It runs on the client alone, and servers do not need it. Files are published for Fabric and Forge for 1.18 – 1.20.1, and the source code is released into the public domain under The Unlicense.
