SERVER OWNERS, Please Read
Server Pack
I update this pack as both a client pack and a server pack. The client pack is the default, but server owners like you, should check the versions tab for the "That Time In Minecraft Server" pack that matches your client version.
What’s different in the server pack?
Client-only mods are removed, so you can drop it straight into the server’s mods/ folder.
Server Ram
About 6–12 GB should be on the server. I found the sweet spot to be around 9–12 GB. More than ~12 GB usually hurts performance because of GC pauses.
server.properties
- Set worldgen:
level-type=terra:overworld/overworld.- If this gets changed after first boot, delete the world folder and restart the server.
- Prevent false fly-kicks:
allow-flight=true.
I know how much of a pain this can be sometimes, so I hope this helps! <3
Spoiler
Thank you to the Tensura:Dungeon devs for letting me use their mod in this pack.Available Versions
