Raytrace Optimization - Creating RT Triggers, Setting Up Level Streaming - Part 2 | UE4

Hello guys, in this video I tell you how to create a trigger blueprint, from which you will be able to turn on and off Raytrace Shadows, Raytrace Ambient Occlusion, Raytrace Global Illumination, and Raytrace Reflections in locations that you want them on or off.
Then I tell you how to set up level streaming, to load and unload specific maps in your level of Unreal Engine 4, thus increasing the FPS substantially!
