Summary
We cannot currently matchmake into private versions of our island on any platform.
Summary
We are consistently getting the “MATCHMAKING ERROR (#2)” message when trying to connect to private versions of our project.
The “Downloading” stage of matchmaking takes an extremely long time even though I have removed all actors and essentially publishing an empty scene. I’m guessing this is Scene Graph cooking the verse.
Launching sessions locally from UEFN works perfectly only private codes matchmaking fails.
Current Behavior
Even an empty scene with a single Scene Graph entity (no props, devices or anything.. just 1 scene graph entity) will fail to matchmake.
Once that entity has any custom Verse component attached (even an empty one), the island becomes unplayable via private matchmaking.
This mirrors the exact same issue we encountered earlier this year on our Kraken project (see previous posts). That issue was never resolved and was worked around by stripping out scene graph completely. Removing months of work on that project.
