Quantum Space Buddies (QSB) is a multiplayer mod for Outer Wilds. The mod uses the OWML mod loader and customized UNET code (internally referred to as QNet or QuantumUNET) for networking.
- Latest version of Outer Wilds. (Epic version preferred, as Steam version is untestable. **We cannot guarantee QSB, or OWML, will work on cracked/pirated versions of Outer Wilds. Do not come asking us for help when using pirated versions.**)
TL;DR - Don't use any mods with QSB that aren't marked as QSB compatible.
QSB relies on exact orders of objects found using Resources.FindObjectsOfTypeAll to sync objects, so any mod that changes the hierarchy at all risks breaking QSB. Also, QSB relies on certain game events being called when things happen in-game. Any mod that makes these things happen without calling the correct events will break QSB. Some mods will work fine and have been tested, like CrouchMod. Others may only work partly, like EnableDebugMode and TAICheat.
**NomaiVR compatibility is currently not planned and likely will never happen, due to extensive changes needed to both mods for it to work.**
- Open port 7777 TCP and UDP on your router. If access the internet through multiple layers of routers, the port will need to be opened on every router.
- Open port 7777 TCP and UDP in and out on your firewall. Some AVs might block you editing firewall settings, so check with your specific software.
- Make sure you are giving your public IPv4 address to your clients.
#### For the client :
- Open port 7777 TCP and UDP in and out on your firewall. Some AVs might block you editing firewall settings, so check with your specific software.
- Sometimes, it has helped to change your network profile to "private".
- Make sure you are putting the right address into the address box.
If nothing here works, many people have got QSB working through programs such as Hamachi. Also make sure you are not running through a VPN while trying to connect.
Note - _nebula has no idea how Hamachi works and has never used it, so don't ask them for help setting it up! As said before, we are tech support for the mod. If you cannot connect to someone, or someone cannot connect to you, **that is not QSB's fault.**
To fix the references, right click "References" in the Solution Explorer > "Add Reference", and add all the missing DLLs (references with yellow warning icon). You can find these DLLs in the game's directory (`OuterWilds\OuterWilds_Data\Managed`);
It is recommended to use the Epic version of Outer Wilds, as you cannot run multiple versions of the Steam version.
A powerful PC is needed for development, due to the high amount of RAM and CPU needed to run 2 or 3 instances of modded Outer Wilds.
It is also recommended to lower all graphics settings to minimum, be in windowed mode, and lower resolution to roughly a quarter of your monitor space. This lets you run multiple instances of Outer Wilds to quickly test QSB.
**Warning : Mod development can lead to unexpected errors in your computer system.**
- **When editing the networking code, mistakes can lead to QSB overwhelming your network connection with excess packets**.
- **Too high RAM usage will lead to Outer Wilds sticking at ~31% loading, then crashing**.
- **There have been instances of graphics cards crashing, and needing to be disabled/re-enabled from Device Manager.**
