Nice sampling vurt!

I've refined my values a bit more for a more subtle blue effect:

static const float3 _depthcolor = _lightfactor * SunCol * float3(0.03, 0.05, 0.07) + (2 * SkyCol + FogCol2) * float3(0.075, 0.095, 0.11);

Morrowind.ini :
UnderwaterColor=012,038,056
UnderwaterColorWeight=0.875


Here are some MGE XE v0.8.10 pics using the above settings:

The underwater shots are really great.. i miss the underwater caustics..

Wow, nice shots. The second values I think look most comparable to what I have seen in real life. I think perhaps somewhere between the first and the second would be good too though.

Agree with Vurt, this looks pretty awesome.

Techy, I'm hoping you may know, but with Phal's SVN 186, I've noticed that if you use exponential fog, the sky no longer reflects in the water surface, is this possible to fix?

Edit: Oops, meant to post in the MGE thread.......

Yeah, this is better off reported in the MGE thread.
Looks like the color of the sky is the only thing getting reflected, not stars or clouds. You can check that the sky color is actually getting reflected on your end by setting a key bind to toggle the sky reflection in the Macro editor and try that in-game (water surface will get a lot more blue without the sky reflection). I don't have a quick solution at the moment - it's something that phal will need to address.

Back on topic... Here are some more pics with a greener theme, this time using MGE v3.8.2 rev-0186:

Modded values:

static const float3 _depthcolor = _lightfactor * SunCol * float3(0.04, 0.065, 0.0525) + (2 * SkyCol + FogCol2) * float3(0.08, 0.125, 0.09);

Morrowind.ini :
UnderwaterColor=015,040,035
UnderwaterColorWeight=0.875

Nice! looks a bit "milky" in that Solstheim shot though, but the other ones are nice.. I think i prefer a dark greenish color of the water, usually how it looks around here.

I came up with this http://piclair.com/data/8lovg.jpg



It http://piclair.com/data/uuny5.jpg though in the distance, looks a bit odd. Any way to fix that?

Yeah. It's more milky from higher vantage points - probably due to my view distance set rather low (5 cells) and fog becoming a factor. I've found it easier to match underwater color with a lighter surface color, but I do very much like the darker colors you've come up with! :rock:


You're using MGE XE v0.8.10 or 0.8.11 with exponential fog and scattering, right? It's likely because of the distance fade-to-blue that exponential fog introduces. I'll have to look at the shader code, or maybe Hrnchamd can tell us what needs to be adjusted.

Correct! Would be great if it could be fixed somehow
