I was looking at using some effects from Windward Mark for my flight sim, before I found out that the software was over a thousand dollars. So I set about trying to recreate some of these effects in the BGE. This is the first I have done, the atmosphere shader. I was trying to replicate the effects as can be seen here: http://www.windwardmark.net/images/screenshots/windlight/urban39.jpg
Here is a model of a city without my shader:
And here it is with:
And here is a simple landscape with it (my grass texture is oversaturated):
Please tell me what you think.
Bear in mind that this is a WIP; anything that doesn’t look right I will gladly change.
Yeah, looks pretty much exactly like you just set the fog start real close, and gave it a long range.
It’s really hard to judge if the shader part is photo realistic when the textures and lighting of the models aren’t. In the city scene you should yellow out the sun a bit, and fix the weird shading issues on the corners of the buildings.
This was running at about 290 FPS with shader, and about 300 without.

It is similar, but for one thing textures are redshifted first, and for another the color is added instead of mixed, to better match reality. It really lets sunlight through better - here is the same scene with fog (same color, distance etc.) instead:
I have no idea what happened to the shadows in that last screenshot - sometimes my textures just turn themselves off (does anyone else have this problem?). Here it is, with shadows this time.
