Cave Horror Project Server Hosting

Almost always the port. Proximity voice chat does not use the normal Minecraft connection, it needs a UDP port of its own, and the default is 24454. Open `config/voicechat/voicechat-server.properties`, set the `port=` line to a port your server actually has available, and restart. If it works for nobody rather than for one person, it is the server setting rather than their client.

6 GB suits a group of around six. This is a mid-weight pack, so unlike a kitchen sink it is not holding hundreds of machine registries in memory. What it does keep busy is custom entities: the pack's stalking mobs are built to persist and follow players, so load rises with how many people are online and how far apart they are.

It is built for it. The quest and event system is multiplayer-aware, and the voice chat plus craftable walkie-talkies exist specifically so a group can coordinate and then lose each other. Some horror packs are really single-player experiences with multiplayer bolted on. This one uses the group as part of the design, which is why it is worth putting on a server.

Because each player exploring separately means another area loaded and another set of the pack's custom mobs being tracked. These are entities designed to persist and pursue rather than despawn quietly, so six players in six caves costs noticeably more than six players in one. It is not a fault, but if you are near the limit, playing together helps more than any config change.

You can, but be more careful than on a sandbox pack. Cave Horror Project has added chapters and reworked quests over its life, and a questline shifting under a group that is partway through it causes real confusion. Read the update notes, back up first, which the panel can do as part of the update, and have everyone move their client on the same day.

The pack's own balance has been tuned over time, including spawn rates for the major encounters, so the shipped configuration is usually the best starting point. If your group finds it too much, adjusting Minecraft's own difficulty and agreeing to play together rather than solo does more for the experience than editing individual mob configs, which tends to break the pacing of the quest chapters.
