Odd visual glitch on random world (terrain data?)

[Tankrizzo]

Hi, running a private 19.3 server with no mods apart from Allocs. I've generated a new 8k random world for multiplayer, we've been playing a few days. The terrain seems bugged in some way - the terrain draw from distance is putting odd elevations in (the chunks are loading fine when you get up close). Played a lot on Navezgane until last week on the server and that was absolutely fine.

 

Tried deleting and reinstalling from the client, same result with fresh install. Deleted all _processed files from the server. Anything else I can try? Really don't want to trash the world if we can help it. Thanks.

So that means the hill in your screenshot vanishes, if you come closer? Or is it "physically" that way as seen in the screenshot?

 

Then bad news: The distant terrain is generated during map generation and never changed or updated during playing. So it seems during map generation something went wrong with distant terrain and i assume there is no way to fix this with your current map.

Yeah it vanishes as I come closer and everything is good. We could put up with it but it makes seeing what's in the distance a bit tricky.

Yeah then it is a bug in the distant terrain. And as it never gets updated after map generation, and there is also no way to force recalculation of distant terrain manually (at least i don't know one), there sadly is no way to fix this.

Thanks LW. I'll discuss with the players what they want to do. First world problems! 🤘

You can turn it off with gfx dt 0, maybe that'll help; won't solve it, but at least you can see over it.

I think I know what I did wrong with this - I inadvertently set the WorldSize to 8096 instead of 8192 in the settings. Generated the world again on a different machine, exact same settings, exact same problem. Regenerating the world with the correct 8192 worldsize works fine.

 

So just to be clear - that world size has to be exact multiples?

You're a Champion thanks for fix.
Just to add to this topic i have been generating maps at whole number eg, 6000, 8000, and had all the same 'fake disappearing' terrain glitches that you encountered. Mine however were just straight vertical walls. loading correct terrain as a walk closer to them. Confirmed with 2 other client PC's had the same issue. Confirming server side fault. Not graphics on client.

Soon as i generated the maps as whole byte values all issues went away.

Worked for me when generating a new random gen map using map sizes in (serverconfig.xml)

"<property name="WorldGenSize"    value="xxxx"/>"

2048 (Smallest)
4096

6144

8138

16384 (Max)
 

Thanks

Yeah the doco is a bit misleading in the settings file as it only gives a min and a max, and doesn't state it has to be a valid byte count. Good to know for the future!
