Iphone Live Link not responding on Ndisplay as frustum after launching from Switchboard

Hi all,

I am posting here in hope of getting help from the community in regards to this issue.

So i would like to do a test of a virtual production using 1 PC, and an iphone. I managed to get ndisplay working well with the live link on my world outliner. I can see the frustum working well in the ndisplay config as well. So when I go to Switchboard, i insert “Unreal” as the editor and insert “Ndisplay”. IP address was on my local IP address, not loopback for both “Unreal” and “Ndisplay”.

When I launch both thru’ Switchboard, I can see my Ndisplay working well but the frustum freezes and the livelink does not seem to work.

Switch my view to the Unreal Engine world outliner and check if my live link works, it works very well with ndisplay.

Im running Unreal 5.4.

I have look through several tutorials and forums but most are using Vive to connect.

If anyone have such issues, or if I am missing a step here, please let me know.

Thank you so much!

***if im missing any details here, do let me know as well!
