Nightly Build on Lan World doesn't seem to send LODs to connected client. (MC 1.20.1)(Forge 47.3.0)
I'm trying to host a forge world opened on my LAN and connect from another pc. I'm able to connect and the f3 info says "Server has full DH support", but the client never builds any LODs. I can confirm this by enabling "Only Render LODs" in Debug and seeing only the void. Distant horizons seems to be working on the host pc without any problems besides an unsurprising bliss issue.
On the F3 info it displays 0 World Gen/Import tasks despite having idled for several minutes, as well it never displays a notification about World Gen/Imports which the host machine regularly displays.
I spent some time hunting down a potentially blocked port, but learned that is no longer needed for DH.
I have somewhat beefy modlist, my next step is to remove all other mods and try to recreate the issue. I'll report back but I'm posting this thread just in case someone is having the same issue. Big respect to DH team for indexing their forums, answeroverflow has solved a lot of issues for me already.
Client OS is windows 10, Host OS is Fedora 40.
I am using nightly build "NightlyBuild_1.20.1-a36cd076-2025-03-02T20_09_11+05_00.zip", downloaded March 2nd.

Try a binary search and figure out which mod is causing it.
So disable half of the mods, see if issue is still there, if yes disable half again etc etc until you find the mod that's causing the issue.
I can confirm the problem still exists for me without other mods(except one) , but without said mods my F3 menu now says "Server does not support DH"
I intend to test again without the remaining mod (Server.properties for LAN) later.
Which mod are you talking about?
Make sure distant generation is enabled on both client and server
I'm coming back to this now, distant generation is enabled on both
The mod is "Server.Properties for LAN"
As I understand it it does what it says, exposing the options in server.properies for LAN worlds as opposed to being exclusive for server .jars
I'm using it to enable "Offline Mode" because I love modded instance launchers but I don't trust them with my account details
Is it possible for you to test on a normal server with only DH? to see if that one mod is the issue?
Yes I believe so I'll report back
Does this mod also enables server side limitations?
E.G. what will happen if the client request chunk from beyond your RD?
In normal single player you can still load it, but a normal server will refuse the chunk request
If the mod enable full server.properties, including server RD it might also block DH from accessing chunks beyond your vanilla RD
My theory would be that DH operates under the assumption that the internal server does not have the standalone server limitation and does not have any safe gourds if a server misbehaves
That is just my theory though
Might be completely incorrect
interesting
I can confirm the nightly is working on a forge server and client without other mods
also I had onlinemode=false set in the server.properties so it isn't that setting in and of itself
