Currently, Reflection capture ignore any ray tracing effects.
So let'say you want to use only ray tracing shadow but also you want to use reflection captures for reflections instead of ray tracing reflections, captured images of reflection captures don't have the shadow from a directional light and it makes reflections unnatural.

Now we have r.raytracing.scenecaptures for scene captures. so wouldn't it be better to have r.raytracing.reflectioncaptures as well?
As a test, I modified a few lines in FDeferredShadingSceneRenderer::GatherRayTracingWorldInstances in DeferredShadingRenderer.cpp and the modification made reflection captures able to capture ray tracing effects.
