Pack setup

How should I set up Techopolis 3 for players and a server?

Use Techopolis_3-12.3.zip as the pack version. Install the pack as its own launcher instance. The creator’s listing does not name a separate server file, so check the release notes before setting up a dedicated server. Do not upload the ordinary client folder blindly.

Client instance Install Techopolis_3-12.3.zip
Dedicated server setup Match Techopolis_3-12.3.zip
Pack loader NeoForge 21.1.235
Java version Java 21

A pack is a matched client and server setup, not one mod with an install-side label. Keep its release, loader, manifest and overrides together.

Referenced mods 208
Client only 20
Server only 0
Not labelled 188

These numbers come from the pack file you chose. “Not labelled” means we don’t know which side it belongs on—not that it is safe everywhere. The file count is not a RAM estimate.

What are the server requirements for Techopolis 3?

The selected pack release is Techopolis_3-12.3.zip. That file is for Minecraft 1.21.1 with NeoForge 21.1.235. This NeoForge setup needs Java 21. It contains 208 mod projects.
