Blueprint: Create/modify and render export cinematic camera in play mode

PROBLEM
In play mode I want to be able to create a new camera with a user-defined transformation and export it to an image file. I want to have control over the rendering options though and create photorealistic render with ray tracing etc (much like a Movie Pipeline Master Config).

WHAT I’VE TRIED SO FAR

  1. I’ve done this with a camera and ScreenCapture2D and can export This all works fine, but I’m unable to control the rendering features. There are no ray tracing option as far as I understand, so the quality .
  2. I’ve attempted to solve it with a level sequence and a cinematic camera attached to it. There’s a nice tutorial about this in the docs and it works. The problem is that I can’t access or modify the camera or seemingly anything else related to the level sequence and its internal settings from within a blueprint. Is this possible, and if so how? If not, would it be possible to do in C++ (and how)?

Any help or suggestions highly appreciated!
