I tried a first prototype using the “Composure” plugin in UE5.1. I followed the example shown here (Unreal Engine 5 ( and 4 ) - Multi Angle Camera Feed to Single Texture Output (6 minutes) - YouTube).
It works well and I get the result I need. Is it however the most efficient technique? I have a heavy scene to render, so I’m looking to reduce overhead to maximise performance.
Quick summary of the technique. You first enable the Composure plugin. You add the four CameraActors to your scene. You create a CompositingElement with 4 CG layers. You override the input of each CG layer to be fed with the Camera actors. You then create a material for the CompositingElement to sample into the 4 different CG layers and combine them into one single output. You can then configure the CompositingElement to output its result into the Player Viewport Compositing Output.
