Interiors and IPLs in FiveM

#IPLs

CreateThread(function()
    RequestIpl('facelobby')   -- commonly used: the Lifeinvader lobby
    RequestIpl('FIBlobby')    -- commonly used: the FIB lobby
    print(IsIplActive('facelobby'))
end)

IPL names come from the game files. Community lists and resources such as bob74_ipl document them; the two above are among the most commonly cited. Loading an IPL is client-side and needs to happen for every player, so put it in a client script that runs on start.

#Interior entity sets

local function setEntitySet(coords, setName, enabled)
    local interior = GetInteriorAtCoords(coords.x, coords.y, coords.z)
    if interior == 0 then return end
    if enabled then
        ActivateInteriorEntitySet(interior, setName)
    else
        DeactivateInteriorEntitySet(interior, setName)
    end
    RefreshInterior(interior)
end

Entity sets are how the same apartment can appear in several styles, or a bunker with or without equipment. SetInteriorEntitySetColor changes the tint of some sets. Without RefreshInterior the change is not visible until the interior reloads.

#bob74_ipl

bob74_ipl is the de-facto standard resource for GTA Online interiors: executive offices, apartments, nightclubs, bunkers, casino and more. It loads the IPLs and lets you choose styles and entity sets in its configuration, so you do not maintain your own list.

• Start it early in server.cfg, before MLOs that build on vanilla interiors.
• Disable interiors in its config that an MLO replaces, to avoid overlap.
• Some interiors require a newer game build — see game builds and DLC.

#Conflicts with MLOs

If an MLO occupies the same space as a vanilla interior that bob74_ipl enables, you get flickering walls or two interiors fighting. Either disable that interior in bob74_ipl or place the MLO elsewhere. The full MLO checklist is in installing MLOs.
