This is a very nice idea Viking.
I've been modifying and upgrading this ENB (it's NOT
created by me)for a lot of time.
Mostly tweaking it to strike a balance between performance and visual fidelity.
I've also spent quite a big number of days tweaking sunrays, godrays and everything it has to do with sun.
Then came along Vivid Weathers and and it kinda blew it a little bit but still retained the rays that I've set in a decent way.
ENB in the initial form it was very low on everything rays, i tried to simulate (to the best of my ability) the way the sun strikes objects to a degree and how would the sun affect the player when looking at it but not without hurting your eyes when you look at the screen and it was harder to achieve then i though.
I think i've tried at least 50 ENB's in the course the course of 4 or 5 years and none of them compared to the work that wolfgrimdark
achieved with his presets.
