Hi everyone,
I’m running into an issue with Live Link inside an Aximmetry 2025.2 project.
In Editor Data mode I can successfully receive Live Link streams.
But once I switch to Cook mode, the characters stop moving — no Live Link data comes through.
What I have already tried:
Configured DefaultEngine.ini with UDP Messaging settings, e.g.
[/Script/UDPMessaging.UDPMessagingSettings]
EnabledByDefault=True
EnableTransport=True
UnicastEndpoint=(IP of my PC):0
MulticastEndpoint=230.0.0.1:6666
bShareSocket=True
bAutoRepair=True
Created a custom BP_MyGameInstance.
Verified DefaultEngine.ini has:
[/Script/EngineSettings.GameMapsSettings]
GameDefaultMap=/Game/Main.Main
GlobalDefaultGameMode=/Game/AximmetryGameMode.AximmetryGameMode_C
GameInstanceClass=/Game/BP_MyGameInstance.BP_MyGameInstance_C
Made sure the Preset is included in the build (tried PrimaryAssetLabel = Always Cook, and also DirectoriesToAlwaysCook).
So far, nothing works — in packaged builds the character simply doesn’t move, as if Live Link never initializes. In Editor everything is fine.
Any advice or working examples would be greatly appreciated.
Thanks!
Hi,
There are a couple of other things you could try:
First, make sure that the UDP Messaging plugin is enabled in Edit > Plugins. (Also, enable all LiveLink plugins that you require.)
Then, confirm that UDP Messaging is enabled in the Project Settings:
In your blueprint, you should use Event BeginPlay instead of Event Init. Additionally, the Is Valid node should be placed after the Delay:
Otherwise, check if your Windows firewall is blocking the connection. You can test this by temporarily turning off the firewall or by creating inbound and outbound rules to allow the necessary traffic in Windows Firewall.
Warmest regards,
