Set up Viewpoint QOL and Simple Mod Check for a server

Separate the server list from the client runtime

QOL's author calls its code client-side while still requiring the server list below. Treat those as separate responsibilities. Do not install a Windows client DLL on a rented server simply because your clients need it.

Preserve entries when adding QOL

The author gives these three entries for QOL. Add them to the existing lines, separated by semicolons, rather than creating duplicate keys or replacing all your other mods.

QOL IDs and the optional checker

Mods=ZombieBuddy;Viewpoint;ProjectViewpointQOL
WorkshopItems=3619862853;3809306528;3811256204

For Simple Mod Check, add SimpleModCheck to Mods and 3812617481 to WorkshopItems, preserving the rest. These lines identify the modules discussed here; they are not a complete list for every model pack or additional mod on your server.

Each player completes the one-time ZombieBuddy setup and approves the QOL JAR when prompted. Confirm a friend's loader indicator before blaming the server list for a local loading failure.

Establish a baseline before enforcing it

1. Use the checker on its author-documented Build 42.21 environment and add it to the server mod list.
2. Keep DoLuaChecksum on. On the Simple Mod Check sandbox page, set Enforce Off for the first run.
3. Have a staff member who can kick join with genuine Workshop files and the required Java parts loaded.
4. Read the server's Logs folder and staff messages. Resolve missing, declined or mismatched files on a test connection before enabling enforcement.
5. Turn Enforce on only after the expected mod set has a usable reference.

Enforce Off is a baseline-inspection step, not evidence that an unchecked client passed. Check a normal player's intended mod set as well as staff setup before inviting everyone.

Understand updates and failed checks

The checker compares SHA-256 fingerprints of loaded Java mods. After an update, the new fingerprint takes effect following a server restart and is confirmed by the first staff member or, by default, three different players reporting it. Missing loader, declined/missing/edited JARs and no report are author-listed failures. Review the exact reason in the log; do not remove checksum checks to conceal a mismatch.

What this checker cannot guarantee

The author describes a failed player's own checksummed client Lua disconnecting that player, with a 20-second failure delay. This is a consistency check for the intended client mod set; it cannot prevent someone rewriting the game client itself.

It also does not prove that every rendering mod, save or GPU is compatible. A camera crash without a fingerprint failure belongs in Viewpoint loading/rendering troubleshooting, not a forced change to the server security baseline.
