Mods supported with MP

Hey guys are the mods supported with multiplayer sessions? My husband tried to join me when mods were turned on and it wouldnt let him. After we turned mods off, he was able to join. Thanks!
Solution:
We deleted the prop one and loaded in just fine. Thank you so much!

In general, assume all players need the same set of mods installed to play together. There are some exceptions. Learn about those exceptions, and how to identify if mods are multiplayer compatible, here: https://docs.ficsit.app/satisfactory-modding/latest/faq.html#MultiplayerSupport

We made sure to download the same ones bc we used mod manager before the 1.0 release, so we knew to do that. Just wasnt sure if there was anything else we could do.

We need more information to help you. Before launching the game again, open the Mod Manager and use the "Generate debug info" option, then send the zip file produced in #help-using-mods. This ensures that your help request won't get buried and forgotten in other, non-help channels! If you need to access older log files, see https://docs.ficsit.app/satisfactory-modding/latest/faq.html#Files_Logs

If you both have the same profile you should be able to play together unless it's a specific mod

He would connect in and immediately disconnect

so without the mod list or whatever errors they faced I can't help just by the description alone something might still be recorded in the log, so send it after they try to join and have the issue

I'm seeing a lot of this kind of error in both of them

Have you seen this before

No, the only thing he saw was that connection to host was lost.

Cause as https://ficsit.app/mod/Factory_Prop_Mod warns:
Factory Props adds an absurd amount of content. This is fine for single player, but can cause significant issues with multiplayer. One such issue, the infamous "Outgoing Reliable Buffer Overflow", can completely prevent your friends from connecting to your game session.
Factory Props - SMR
The Ultimate Decorating Toolkit!

Aaah ok. We will try and delete that one, then restart.
AngryBeaver
AngryBeaver4mo ago
Well if it is that it's the combination of both Decoration and Factory Props One or the other alone might be enough, do some testing
JenM
JenMOP4mo ago
Ok, doing that now.
