[RELEASED] for UE4: Complete Sky and Weather System

Up to now, is still extremely unstable and often crashes in version 4.22 of the engine in the mode of light tracing and DX12. Then prompt for insufficient memory and exit the engine.

Ray tracing in 4.22 is great, but is too messy in DX12 mode. Frequent crashes make almost completely unavailable in DX12 mode. It’s really terrible. Until the latest version of July 19, it still hasn’t been fixed. I don’t even know if problem will be fixed. 。 If not, that means is almost completely unavailable with ray tracing or DX12.

I used WIN10 1809, 2080TI, Unreal 4.22.3 to test, and also tested on other devices. The test results were all consistent, unusable and frequently crashed.
