Landscapes Reimagined Genesis server files

No. Landscapes Reimagined Genesis has no separate server pack on Modrinth, so the server is built from the .mrpack: the Fabric server for Minecraft 1.20.1, plus the pack's overrides folder and the server-side mods its modrinth.index.json lists. A modpack installer does this for you; our guide shows how to make a server for a modpack with no server pack.

How much RAM does a Landscapes Reimagined Genesis server need?

Players online	RAM	DSN plan
1–3 players	About 6.5–7.5 GB	Premium (8 GB)
4–8 players	About 7.5–9 GB	Heavy (12 GB)Premium (8 GB) can do if players stay close.
9–15 players	About 8.5–11.5 GB	Heavy (12 GB)

Estimated from 264 mods on the server with our RAM calculator, not measured: low end if players stay together, high end if they spread out.

By this estimate Premium (8 GB) can run a small group. Our pick below, Heavy, leaves room for more players and for the pack growing with updates.

Set Java's heap (-Xmx) 10–15% under the RAM you have, about -Xmx10500M on 12 GB. Fabric 1.20.1 takes it in the java command (-Xmx), usually in the start script. RAM guide.

Start it and accept the EULA.
Run the start script in the server files, or java -jar on the Fabric 1.20.1 server launcher, then set eula=true in eula.txt if you accept Mojang's EULA (EULA step). With 264 mods, the first start takes minutes.

Let friends connect: forward TCP 25565, or use a tunnel or host behind CGNAT (can't connect?).

Or run Landscapes Reimagined Genesis on DSN

How to play Landscapes Reimagined Genesis with friends

Each player installs Landscapes Reimagined Genesis version 3.2 with the Modrinth App or Prism Launcher, the same version as the server, and adds the server's address under Multiplayer.

Different versions of Landscapes Reimagined Genesis on the server and a client show up as Mismatched mod channel list or mod rejections. Why friends can't join, timeouts included.

Lag and performance on Landscapes Reimagined Genesis

Can't keep up! Is the server overloaded? means ticks take longer than 50 ms; more RAM won't fix that once Landscapes Reimagined Genesis has enough (tick lag guide). For Landscapes Reimagined Genesis:

Measure first: spark's /spark tps and profiler work on 1.20.1 and name the mod or machine using the tick time.
Distances: view-distance=8 and a lower simulation-distance in server.properties.
Pre-generate: Chunky for 1.20.1, /chunky radius 3000 then /chunky start, before people explore.
Chunk loaders keep machines running with nobody nearby; in a pack this size, dozens add up.
