Can live link change the default port?

Hi there,

I wonder if the unreal could change the live link default port? We know that the default port is 11111, can I change it to some other ports, like 11112?

Any response will be appreciated, thank you so much!

Hello,

I never tried, but maybe look at the Project settings → UDP messaging → unicast/multicast endpoint settings?
Sorry, just a blind guess.

Also, BaseEngine.ini file has LiveLinkPublishing port setting, not sure if it is the right one, there is also ini for Apple Kit.

Hope that can help.
Regards,
Alex.

Thank you so much for your reply!

I have found the LiveLinkPublishing port setting in the BaseEngine.ini file, it seems that it will change the all live link port for the unreal engine. But I just want to change the live link port for each project…Because I want to start two projects on the same laptop, and send the live link data to each project separately.

And I think the first way is just to change the listening port of the whole project, not the live link port? Sorry about my English, sometime I didn’t clearly express myself.

Hi Alex,

I chenged the ini file and directly package the project, it works! Each project has their own live link port, and I can send different face data to each project.

Thank you so much agagin! XD

Has anyone found a solution on how to change the default port for an already packaged game?

For our usecase, repackaging the game every time and having to change the project settings within the Unreal Engine Editor is really time consuming at the moment and won’t work in the long run when it comes to scaling the project.

We use “Project Settings / Plugins - Apple ARKit / LiveLink Publishing Port = 11112” to set the new Port and then package the game.
Within the packaged game there is a folder with many config files, which appears once you start your game for the first time: Windows/YourPackagedGamesName/Saved/Config/Windows/
But unfortunately none of those config files contain the publishing port, so I guess it’s value is set somewhere else and I can’t manage find it.

Would be great if somebody has figured this out and could share their knowledge. Thank you :slight_smile:
