Water color tweak for more realistic oceans
« on: September 16, 2013, 02:15:45 pm »

I tried to make water looking more realistic than default one, which appears to me way to bright, blue and plastic.
In particular enviroment/sky reflection is somewhat off. I know, your engine is ever evolving and water rendering will not stay the same as it is now.
But for what we have now, tweaking the atmosphere and water settings give quite good results imo.
It isn't whitout side effects on sky and terrain lighting though.
Mainly I reduced  beta rayleigh and water settings.

That looks nice.

There were several changes in the water rendering since the latest version, more detail added to the water surface and the lighting model changed - especially when the sun was lower, the water was too bright previously, not taking into account the angle.

Are those two screens using the same sun position?

Yes, same sun position, same time of day, location around Seattle.
As you can see, the reddening of dawn atmosphere is gone too.
The tweak works best for lower sun positions, not as good for high noon, when reflections are reduced.

The sky seems a bit grey, in the distance the mountains have grey in front of them.

That tweak looks amazing. Why does the sun seem so different? The shadows don't move so I know it is the same.

Indeed! I think Brano should set those settings as default in the next build if you ask me.

Okay, tried it - while it looks good on that one screen of yours, it doesn't work elsewhere very well.
Basically it has almost removed the atmosphere, suppressed the atmo color saturation, erased the feeling of distance. Water rendering changed in my version, so the water color on my screens is different:


Terrain reminds me of atmosphere-less flight simulators, and the sky of overcast or smog, although in that case the visibility would be much lower.

First impression, it looked nice but the facts speak for themselves I guess  :)

Am i the only one here, who thinks the old version looks more realistic?

The problem here being noone REALLY knows what it is like to float hundreds of feet up in the air and look across mountains and plains and across the oceans. We all just expect a nice clear view of the world and that damn hazy atmosphere messes up the view.

Stand on the ground with a mile of view distance and you hardly notice it. But outerra screens hardly end after a mile.

EDIT:: Just to be clear. The water does look WAY better in the modified screens but is just too clear. That blue in the original is way too blue blue type blue but has the right opacity. So a less blue ocean and a more foggy water. Yes.

It seems to be a matter of taste as almost everything. Some like punchy colors, some like it less cartoonish.
My focus was  only on water rendering at lower light conditions. If we could get there without touching the atmosphere settings it would be nice. I wasn't able to do it without reducing these parameters.
You are right, sky and terrain appearance is quite a bit affected. So it would be good to have an extra color saturation adjustment for the water.

Yes, I like them. Looks much more realistic.
And yes, please leave the dust. It's more realistic anyway.

I did another try, now for a mid day setting with "thicker" atmosphere.
Attached are comparison screens tweak vs default and the world.cfg.
