Notes

As mentioned by IMS in the Iris 1.8 alpha 3 support thread, the Sodium method net.caffeinemc.mods.sodium.client.world.LevelSlice.method_22336 (getLightEngine) is called here, in Nostalgic Tweaks, instead of the vanilla net.minecraft.world.level.BlockAndTintGetter.getLightEngine (for some reason?), which will only throw UnsupportedOperationException, which kills the game.

Beta 9 is now version locked to Sodium 0.5.x. An update will be needed to support Sodium 0.6.x.

Great, that's fine!
