InCameraVFXExample project, can I use it with a Vive Tracker?

Hi guys! I was looking into Virtual Production and I was hoping to throw something together as a proof of concept. I got excited when I found that UE4 now includes a sample project for setting this up! There’s stuff I’m unfamiliar with, like nDisplay and LiveLink, but after reading through the Quick Setup guide, I don’t think I’ll need those. I’m hoping to use a Vive Tracker to get my Camera position, and I was hoping to run the project on a single computer, using the attached monitors as “LED screens”.

Without changing anything in the project, when I hit the Launch button, I immediately get a fatal error. After doing some digging, it looks like it has something to do with the Get Actors blueprint node running in development mode? The InitializeAndShowLists function in the BP_IncameraStageSettings blueprint has that node and looks to be the culprit, but it might just be a red herring.

I’m new to development in Unreal and using the Unreal Forums, so please forgive me if this isn’t the right place to ask this question. What do I need to do to change the project to run on one computer, using the monitors as LED screens, and using the Vive Tracker for camera tracking?

Here’s the documentation I was trying to follow. In-Camera VFX Quick Start | Unreal Engine Documentation


You need to set the Tracker code in the ndisplay cfg and then get vrpn server running, once these things are running use get vrpn tracker data node in blueprints from ndisplay api node. And type your tracker id string.
