FusionWhitelist

Fusion Whitelist 1.0.0

Lock your BONELAB Fusion lobby down to the people you actually invited.

What it does

Adds a page to BoneMenu where you can flip whitelist enforcement on or off and manage a list of allowed SteamIDs. When it's on, anyone trying to join who isn't on the list gets rejected before they finish connecting. The host is always allowed in, no matter what.

Toggle whitelist enforcement on/off from the menu Add or remove SteamID64s right in-game Paste in a batch of IDs at once instead of typing them one by one Everything saves to a JSON file in UserData, so your list survives a restart Edit that file directly if you want, then hit "Reload Whitelist from File" to pick up the changes without relaunching Setup

Drop the DLL in your Mods folder alongside BoneLib and LabFusion. Open BONELAB, go to BoneMenu, and look for "Fusion Whitelist." Turn it on, add your friends' SteamID64s, and you're set.

Notes

Only the host enforces the whitelist, so this only matters when you're hosting. If enforcement is off, everyone can join like normal.

Requires BoneLib and LabFusion.
