Ah your pictures showed it exactly. Even though mine was in the same place, the weather conditions were different because I didn't have the warm sunset across the sky like in the first one. However, if you look at your photo without sunglare, you can see all the subtle pinks and blues and how they play along the clouds. The one with the sunglare are basically the same colors but all the beautiful subtlety is washed and faded out from the beam. This is what I've been noticing on my game as well.
The Gods Ray mod looked nice - wonderful beams - but even way brighter than beaming sunglare so I'm sure it's going to wash out even more color at sunsets, but I'd like to give it a try too.
I have some tweaks to godrays shader, it won't brighten up the screen excessively anymore.
You have better eyes than I do.
I see difference in the water, but not much in the sky.
I liked God Rays a lot when trying it out, but it doesn't work nicely with HDR and I need HDR for RAEVWD so I had to let it go.
It was a test version, an alpha version. It has some problems. I want to know about your problems, that way I can work on a fix.
Be sure to check new versions when they come, I have a couple of fixes for new version that you may like.
