FAQ
S4MP is completely free to play on the public version via LAN, although, there is the early access Patreon version with online access and newer features that will eventually roll out for the public version as well.
Not at all! You will be able to use the downloaded version of S4MP with its features, but it will become restricted to LAN only until renewal.
Link your Discord in your Patreon settings and it will automatically give you the role.
Yes! Crossplay is supported by S4MP between PC, Mac, and any game launchers.
You can, but only with EA & Origin! More than one can connect to the same account at a time, this will force you to be offline but still be able to play The Sims 4.
Unfortunately, you can’t due to Sims 4 limitations, you can only play in the same household and travel together even if the other sims are left at home.
If you want to experience the pack’s content, yes! You can also toggle the packs to your liking in S4MP’s launcher settings, so that everyone has the same content loaded, to prevent issues.
You may still be using the public version, please manually download the latest early access version instead.
After manually downloading the early access launcher, log into it and access the settings tab to discover your invite codes and registration link.
We usually discontinue the Online servers for older S4MP versions, so make sure that you’re up to date by using the latest version available.
Yes! Just make sure that all players have the exact same CC & Mods installed on their computers. Do keep in mind that not all scripted mods may be compatible with S4MP, causing other players unable to interact with objects or Sims.
We recommend that the host is the only one to save, then you can all exit.
You can CTRL + Shift + C
to open the console and type chat <your message>
, you won’t see the message being displayed but others will!
It’s quite a random issue that we haven’t found what triggers it yet, but there are some temporary fixes! – The host could try using “Save As…” instead of the quick “Save” to prevent it from happening, and also, try to avoid traveling from home to point A and then point B, C, etc. It’s best if you return home so that the mod copes up before going somewhere else.
Unfortunately, seems like this feature doesn’t fully work with EA’s new launcher. Please follow this guide to manually toggle your packs, then run your game manually instead of the Start Game button.
This could be caused by S4MP not being fully allowed through your Firewalls, your VPNs not connecting properly, incompatible and/or missing mods on someone’s end.
