How to make a Guns, Cars and Morph server on your own PC

What's specific to Guns, Cars and Morph, step by step. The full walkthrough for any pack: how to make a modded Minecraft server.

Install Java 17.
Check with java -version. Java version chart.
Get the server files.
Download the official server pack, GunsCarsAndMorph+Server-[2.1.1].zip, from CurseForge and unzip it into an empty folder.
Start it and accept the EULA.
Run the start script in the server files, or the run.sh / run.bat the Forge 1.20.1 installer writes, then set eula=true in eula.txt if you accept Mojang's EULA (EULA step).
Set the RAM with -Xmx, sized from the table above.
Let friends connect: forward TCP 25565, or use a tunnel or host behind CGNAT (can't connect?).

Or run Guns, Cars and Morph on DSN

How to play Guns, Cars and Morph with friends

Each player installs Guns, Cars and Morph version 2.1.1 with the Modrinth App or Prism Launcher, the same version as the server, and adds the server's address under Multiplayer.

Different versions of Guns, Cars and Morph 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 Guns, Cars and Morph

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

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.

What a Forge 1.20.1 server running Guns, Cars and Morph hits most. For any other error, paste the log into the free crash log analyzer.

Wrong Java version. Guns, Cars and Morph on Minecraft 1.20.1 needs Java 17. Started on Java 8, it stops with UnsupportedClassVersionError: ... class file version 61.0, this version of the Java Runtime only recognizes class file versions up to 52.0. Java version fix.
Out of memory. Guns, Cars and Morph (35 mods on the server) needs about 2–2.5 GB for 1–3 players; java.lang.OutOfMemoryError means it ran out. Out-of-memory fix.
Client-only mod on the server. Guns, Cars and Morph includes 14 client-only mods, which a server install skips; copying a player's mods folder brings them back and stops the server. Check a mods list with the client-or-server-side checker. Client-only mod fix.
After adding or updating a mod. Mods you add to Guns, Cars and Morph by hand usually crash it with a missing dependency or a mixin conflict.
Ticking entity or block entity. The crash report names it and gives its coordinates. Ticking entity fix.
