Quick facts

Create & Explore (C&E) server files

No. Create & Explore (C&E) 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 Create & Explore (C&E) server need?

Estimated from 106 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 Standard (4 GB) can run a small group. Our pick below, Premium, 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 -Xmx7000M on 8 GB. Fabric 1.20.1 takes it in the java command (-Xmx), usually in the start script. RAM guide.

Lag and performance on Create & Explore (C&E)

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

• 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.
• Create contraptions and train networks tick in every loaded chunk; check them first when TPS drops.

• Wrong Java version. Create & Explore (C&E) 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. Create & Explore (C&E) (106 mods on the server) needs about 3–4 GB for 1–3 players; java.lang.OutOfMemoryError means it ran out. Out-of-memory fix.
