Raytrace Optimization - Creating RT Toggle Widget, Setting Up RT Lights & Tips - Part 1 | UE4

Hello guys, in this video I give you a quick overview of the different types of Raytracing, tell you how to create an RT toggle button, from which you will be able to turn on and off Raytrace Shadows, Raytrace Ambient Occlusion, Raytrace Global Illumination, and Raytrace Reflections.
Then I tell you about some tips about how to decide which RT setting to enable in which part of your level, and reasons why you should not enable multiple RT settings.
After that I tell you about how to increase FPS when Raytrace shadows are turned on, which is done by disabling "Cast Raytraced Shadows" in all the unnecessary lights.
I also tell you how to remove the "Harsh" shadows that might appear if you enable multiple RT lights in one scene, or if you enable RT Lights that cast RT Shadows in conjunction with normal light.
