Rendering multiple scenes

How would I go about rendering 2 different scenes in their own viewports?

I know how to set up multiple viewports and render the same scene from different camera angles,

but I want to have 2 independent scenes all together. Does it involve creating a Scene Processor?


Just attach different scenes to those viewPorts, e.g.:





had been doing that and getting errors,

but found the solution - I need to do an updateGeometricState() on anything before attaching to a viewport.
