Hi dear Patrons, 

here's a shader I implemented from this GPU Gems article: https://developer.nvidia.com/gpugems/GPUGems3/gpugems3_ch13.html

The effect is called Volumetric Lihght Scattering or God Rays, and is achieved in a post processing shader, by rendering every object two times. 

I'm here for any questions, enjoy! 

Thank you a lot for your support 

(Fixed a line in the shader code which would cause an error in Mac systems)
