"It’s been 10 years, but I finally found the solution here. Check the output log to see if seamless travel is actually working. You’ll often see a message like this:
LogGameMode: Warning: ProcessServerTravel: Seamless travel is disabled in PIE. Set net.AllowPIESeamlessTravel=1 to enable.
To fix it, simply either enter net.AllowPIESeamlessTravel 1
in the console or add the following to your DefaultEngine.ini
:
ini
CopyEdit
[/Script/Engine.GameNetworkManager]
net.AllowPIESeamlessTravel=True
This worked for me. Hope this helps, and have a great day!"
