Hi Tomas,

You can get the tracking and video inputs of 8 cameras simultaneously. You can use for this the [Common_Studio]:Compounds\TrackedCam_Unreal\TrackedCam_Unreal_Prev_8-Cam_3-Billboard.xcomp compound. With this compound, you can easily switch between the different inputs.

However, one computer can render only one Unreal camera due to the limitations of Unreal. Usually, one computer wouldn't have the resources to render more than 1 virtual camera view anyway.

If you don't just want to switch between different input videos, but you need to render more than 1 video output simultaneously with Unreal, then you can use a multi-machine setup to render all 8 cameras simultaneously: https://aximmetry.com/learn/tutorials/for-studio-operators/multi-machine-in-a-large-studio-environment/

Warmest regards,
