cave culling questions
hi, I've got a few questions about how cave culling works.
are caves culled during LOD generation, rendering, or both?
if during generation, would temporarily disabling cave culling to make cave LODs only for a certain section of the world be enough to make them render for that certain area later?
if rendering, can you render cave LODs in already-explored chunks by just temporarily turning it off?
if both, if you turn it off, generate cave LODs, view them (for a screenshot, or whatever), then turn it back on, will the generated cave LODs still be there for viewing without having to be regenerated later on?
thanks a lot!

to follow up: if any of these methods are valid, would adding in a way to turn it off automatically when below a certain height and/or within a certain area be feasible? this way, you could only generate/render them when they are needed (underground, in a big cave)
Pretty sure the cave culling option specifically only affects rendering, not generation
The generation is affected by world generator settings
I think setting it to surface will cause it to not generate anything underground
Surface will prevent stuff like structures or trees from generating
It’ll still generate caves?
i see, so i should be able to just turn off cave culling when in a big cave underground and load the LODs for it?
yes
doesn't seem the case, actually
ill try exploring that area again
exploring it again worked
...and turning cave culling on again doesn't un-render the caves. huh.
so it looks like it might actually be case #1?
Cave culling only affects rendering, not world gen.
However, world gen by default attempts to skip most cave generation to speed up the process slightly.
