Sodium has settings for culling entities and block faces. Do I need to disable any of these when using with your mod?

From the modpage:

Thanks, I read the modpage. But I asked if I should turn this Sodium feature OFF or if it should be ON. The question was: what is better from your point of view, to enable the culling function in Sodium or not (using it with your mod)?

Just leave it ON. There is no reason to turn it off or ever change that setting.
