Vive Mars Tracking (Live Link) not working on nDisplay Render Nodes

Development Cinematics & Media Virtual Production

Hey, We trying to use mars tracking with our two render nodes for virtual production in unreal engine. We get the tracking into Unreal with live link. Inside the Editor its all working fine. As soon as we launch nDisplay with Switchboard there is no tracking anymore.
We already tried a lot and none of the following helped/worked: We set all IPs manually (nowhere any 127.0.0.1),
We set the UDP Message in the Project Settings,
We saved a Live Link Preset wit rebroadcast in the Project Settings, which is still there when we open Unreal again.
We entered “-messaging” in the extra cmd line args
We entered a Unicast Endpoint in switchboard for every render node.
We checked if every render node gets tracking by just manually opening the unreal project and checking live link.
We added the Live Link component to the nDisplay Blueprint and also tried adding it outside of the blueprint to a camera and object.

We don’t really know what to do anymore and I hope somebody maybe still has an Idea and can help us.

Thanks a lot in advance!

Having the same issue, have you found a solution?

We solved the issue but I could not really remember what the problem was. There were several issues as I remember.

Did you make sure you set all these things correctly:

Also check if the UDP Static Endpoint Port is set correctly and the LiveLink Preset is set in the Project settings.

Then we also made the mistake that our custom CineCameraActor is not a child of the nDisplay Actor. Make also sure that the nDisplay ICVFX Camera to Control is your custom CineCameraActor.

Also check if the Viewport Option is set to “Mesh” in the nDisplay config. I think this is not the default.
