Update from 1.21.4 to 1.21.7 (Terralith+Terratonic)

[eternal pond]

Hello,

I'd like to update my server to 1.21.7, now that all the plugins and datapacks I need are up to date. The problem is that, despite the fact that Terralith and Terratonic are marked as compatible with 1.21.7 (Terralith updated, Terratonic already compatible), I'm having major link problems when generating new chunks. I haven't found any similar problems by searching on the internet, it's probably still too recent.

I'm on PaperMC 1.21.7 (v21)
I'm using the datapack version, hence the use of Terratonic, and not Tectonic.
Here are the datapack versions I use:

• Terralith: Terralith_1.21.5_v2.5.11.zip
• Terratonic: terratonic-3.0.0-datapack.zip

Images :

• 1st : zone where I am located generated in 1.21.4, zone opposite generated in 1.21.7
• 2nd : zone where I am located generated in 1.21.4, zone opposite generated in 1.21.7

Thank you for your time and your help ! 😊

Same here :

• 1st : zone where I am located generated in 1.21.4, zone opposite generated in 1.21.7
• 2nd : zone where I am located generated in 1.21.7, zone opposite generated in 1.21.4

I think that’s because of Tectonic being updated to v3 which was a major revamp, its terrain changes noticeably differ from v2. I know the mod version has the capability to blend the chunks together slightly but that’s not possible with the datapack version

For the moment it's on a test server, it hasn't affected my real server, is there any way of preventing these problems from happening? Or am I stuck with the old version ?

I don’t think there is a way to stop it with the datapack but you could always ask in the server for tectonic https://discord.gg/HCGX94d6

Hello !
I found a solution to use the Tectonic datapack v2.4 (Terratonic datapack v3.2) in 1.21.7 with your last Terralith version natively compatible with 1.21.7 (so the unique difference between my server in 1.21.4 is Terralith version), and I have the same problems of generation between old and new generated chunks (less violents because biomes seems good, but the links are very bugged)

glad to hear!

I don't think you've read all of my message 😅 , I'm still having the same problems despite using Terratonic in an older version (before v3), whether with your Terralith datapack in native version 1.21.7, or in version 1.21.4 modified to works in 1.21.7... 😭

as the screenshots show

im a bit confused, is this just terralith? updating terralith without updating tectonic? other way around? updating neither, but updating to 1.21.7?

Here is all my tests :

• Minecraft 1.21.4 with Terralith 2.5.8 and Terratonic 3.2 (based on Tectonic 2.4.0a) : it works currently
• Minecraft 1.21.7 with Terralith 2.5.11 (1.21.7 native) and Terratonic 3.0 (1.21.7 native) : bad links between old and new generated chunks
• Minecraft 1.21.7 with Terralith 2.5.11 and Terratonic 3.0 : bad links between old and new
• Minecraft 1.21.7 with Terralith 2.5.11 and Terratonic 3.2 (based on Tectonic 2.4.0a) modified to run in 1.21.7 : bad links between old and new
• Minecraft 1.21.7 with Terralith 2.5.8 and Terratonic 3.2 (based on Tectonic 2.4.0a) both modified to run in 1.21.7 : bad links between old and new

And I use datapack version because I’m in PaperMC

gotcha, so no matter what combo, updating to 1.21.7 has bad borders

@thick mesa do you know if this is cause of the weird terralith chunk border thing nobody could solve when it appeared back in 1.21.4, or is it different / related to terratonic?

[fast oyster]

might be worth bringing it in the Tectonic discord so apollo can see it

Thank you for your help. It's already done, at the same time as I posted it here. For the moment I've resolved to have problems with links between my chunks 😕
