[Feature Request] Providing an interface for custom Ray Tracing Shaders

Hi all,

First of all, I really enjoy the new raytracing features that UE4.22 provides. I was immediately interested in creating my own ray tracing shader & code so I started looking at the RayTracingDebug.cpp to get a feeling on how it is achieved.

Sadly, I found out that all dependencies of the code come from DeferredSceneRenderer as it is more or less hard-coded into the rendering pipeline which is excluded from the API.

So there’s currently no way to obtain the current RayTracingScene outside of the DeferrredSceneRenderer.

A custom raytracing pipeline would be perfect for a high-performance Lidar sensor simulation. (Current implementations require cubemap rendering or CPU-based raycasts).

Are there any plans to make ray tracing more accessible via either the access to the RayTracingScene or even via postprocess materials??
