UKismetRenderingLibrary::EnablePathTracing

function Engine Blueprint Since unknown

#include "Kismet/KismetRenderingLibrary.h"

Access: public Specifiers: staticUFUNCTIONBlueprintCallable

Description

Enables or disables the path tracer for the current Game Viewport. Equivalent to the ShowFlag.PathTracing console command but callable from shipping builds.

Caveats & Gotchas

• Requires the path tracer to actually be supported by the current RHI/hardware (DirectX 12 with a compatible GPU); on unsupported platforms this call has no visible effect.
• Path tracing is extremely expensive and not suited to real-time gameplay framerates — this is intended for offline-quality preview/cinematic capture, not shipping gameplay rendering.
• Being callable from shipping builds is unusual for a rendering debug feature, but it does not bypass hardware/RHI requirements.
