Missing/Duplicated Chunks
I just got my first PC after way too many years, playing with DH and shaders for the first time, etc. Anyway, I've been trying to get a singleplayer world going, but after two days of troubleshooting, I've arrived here, which is the best result I've achieved so far, but still has two major issues.
First is a band at mid-range that isn't rendering in (but closer and further do). I thought it was a "wait and they'll load" issue, but several hours later and no other chunks loaded in. I saw in the FAQ that Chunky was not recommended, and I have used chunky to generate a 1000 radius circle, but even if I load with my player in survival, it still won't render, and it is always the same chunks that load/don't load. I see that you suggest "DH Internal Server Mode" but I don't really know what that is, or if this is a Chunky/DH issue to begin with, or that can be resolved. (By the way, resetting the world is not a problem since I haven't actually done anything on it yet.)
The second is much stranger, and I haven't seen anything quite like this. At a high enough level, the terrain will vanish, and a second, identical world will appear far below it. It's positioned about -2k below and vanishes as soon as I get close enough to it. I have no idea what is causing that one.
Here is everything that I have on the world/setup to help.
Fabric 1.21 10/32 GB RAM
Iris/Photon shaders (problem persists even without shaders, however)
Larion world generation with WWOO datapack (I've seen videos of both working with DH, so that shouldn't be an issue)
Chunky (saw several tutorials suggesting it, but now perhaps a problem?)
DH (obviously, but only on 2.2.1 because 2.3 doesn't exist for 1.21)
C2ME (latest version for 1.21 but perhaps not helpful with DH 2.2 as per #faq-general?)
Standard performance mods:
dynamic fps
entityculling
fasterrandom
ferritecore
immediatelyfast
noisium
sodium
Various QOL mods, but nothing that should mess with DH afaik. Hope that's helpful. Thx!

Pictures didn't post? I don't know, discord is weird sometimes.
DH 2.3 for MC 1.21.1 should still work on 1.21
Though you should update to MC 1.21.1, all the mods should be compatible
It fixed some critical exploits
Solution
The holes looks like Chunky caused holes
/chunky
Using Chunky to pregenerate for DH is not recommended for several reasons. The first one is the swiss cheese that might show up when using chunky while DH is installed. The second reason is that it's pointless, as DH has a build in pregenerator that is better integrated than chunky:
- It saves space by only storing LODs, not normal chunks
- It is faster to use DH's pregenerator to generate the LODs than first using chunky to generate the normal chunks, and then using DH to convert the normal chunks to LODs
- It is part of DH, and therefore always/only called when DH needs it
- Chunky calculates it's radius in blocks, confusing the user if they are not aware of this
Distant Horizons' built-in LOD pregenerator is enabled by default, and can be sped up or slowed down by changing the
Cpu Load in DH's settings, or disabled by turning off Distant Generation.
If you want to pregenerate both LODs and normal chunks, set the Distance Generator Mode to Internal Server under Advanced, World Generator. This will of course take up quite a lot more storage space. Make sure you have C2ME installed if you want to use Internal Server, as the generation speed will be crap if you don't.
Note, this also applied to other similar pregeneration mods.
Try deleting all your LODs and start again

Sometimes there might be 2 additional files next to the main one with extensions .sqlite-wal and .sqlite-shm
If there are, all 3 should be treated as a single file, a.k.a. moved, deleted, backed-up always together!
If you don't, the database will become corrupted./slowgen
World generation in general is quite slow, if you want to speed it up:
Install Noisium, Lithium and C2ME(DH 2.3.0+). These mods can improve generation speed by a bit, but it will still not be fast.
Increase
CPU Load in Distant Horizons settings for faster generation, but you will experience more lag spikes and stuttering due to heavier workload on CPU.
To see if Distant Generator is really working or not:
1) Check CPU usage while in-game, using Aggressive settings of CPU Load. If CPU usage's hovering around 80-100%, the LoDs are generating in the background.
2) Go to DH settings > Advanced Options > Debug > Wireframe, set Enable Debug Wireframe Rendering and Show World Gen Queue to True.
Enabling both settings will show you the visualization of world gen tasks queued and working on the map (blue boxes for queued tasks, red boxes for working tasks)You can do the second part to see where DH generates stuff
As for duplication no idea, maybe some old 2.2.1 bug
Okay, that sounds like it could be it. I'll probably just delete the save and restart with the same seed to make sure there's nothing left from the old and to avoid accidentally corrupting or messing something up by resetting it manually. I'll try to get a 2.3 version to work w/ C2ME and get rid of Chunky.
By the way, are these critical exploits anything I should worry about playing in singleplayer? Because that's pretty much all I do...
Nope
But you should still use 1.21.1 regardless imo
No downsides
It's just that I have some other mods I've grown quite attached to that only go up through 1.21. In any case, DH generation seems quite normal now that Chunky is gone, and I'm not seeing any duplication either. I'm going to see about potentially adding some structure generation mods, maybe, but either way thanks for the help. Marking this as resolved.
