How to make Scene Capture Component 2d to capture Ray Tracing reflections instead of SSR

Is it possible for Scene Capture Component 2d to capture Ray Tracing Reflections? In realtime.
(Not for games, so I don’t care about optimisation)

Because there is GRayTracingSceneCaptures variable in the source code of the last UE4 engine version, which you can use it to enable the capture. It is just supported in recent.



static int32 GRayTracingSceneCaptures = 1;
static FAutoConsoleVariableRef CVarRayTracingSceneCaptures(
    TEXT("r.RayTracing.SceneCaptures"),
    GRayTracingSceneCaptures,
    TEXT("Enable ray tracing in scene captures.
")
    TEXT(" 0: off 
")
    TEXT(" 1: on (default)"),
    ECVF_RenderThreadSafe);

Is this variable available via Blueprints?

Yes, you can use “Execute Console Command” to run it in Blueprints.

And you can also set the variable in ini file.
