Tell me how to receive live links from UE5.4.

Software Unreal Engine
1

To link with UE5.4 live link, I built a file using cmake and activated live link in the engine, but no data is received.
I changed 230.0.0.1 to 127.0.0.1 because I don’t get live link data from an external server, but I get it locally, so why isn’t it coming in?

Trying to load default config file ‘ZEDLiveLinkConfig.json’
Unable to read json config file.

Hi,

It says “Unable to read json config file”. Can you make sure to give the config file as an argument when running the sender?

You might need to change the connection_type to UNICAST (in the config file) as you changed the ip address.

Best,
Benjamin V.
