Sending UE4 studio to 3 led walls in studio

I’d like to be sure, how should I create virtual environment and send it to my led walls.
I have simple 3 led walls with 90degree (left,central back and right). Am I right that I need to create 3 cameras in my project (with FOV 90deg), place them in one point, attach them to my vive tracker position and send (I’m using Blackmagic 8K PRO) them to separate outputs?

I did virtual events, but just with green box and one led wall, but I didn’t work with 3. The idea is to attach vive tracker to my real camera and shoot this led virtual studio.
Any ideas how to start?
