Hello Thorsten, First again sorry when it sounded like rant. But I must admit I was dissapointed seeing the results on my system here.

Thanks for that detailed explanation! I didn't see any error messages in the console so I guessed there shoulden't be any shader-problem, but good to know that there should be a change to see from the ground. > Actually, no.

So my second > guess is that you don't have an nVidia card. I actually have a new nVidia Geforce GTX460 with 1GB RAM. So that should be not the problem. I have tried with the skydome shader button on, and the effect was even worse. All colors went dull..... So indeed for any reasons the shader seems not to work here. > The GUI is actually rather fool-proof - it switches almost everything > which is not compatible with the scheme off no matter where the sliders > are > and parses only the sliders which are implemented.

Which should be no problem, as from reading here on the list from time to time I can see that it is even wished to make this work available for Default Weather as well. Not all people can run Advanced Weather without having a bigger unusuable fps impact; on my system here (DualCore 2,6Ghz with 4 GB RA) framerates are now worse than with Default Weather.

I can still remember my first and second flight as pax in a glider 15 years ago. The scattering effect was even visible from 1000-1500ft AGL, visibility wasn't that great as you show in your screenshots. (less than 100km visibility) I actually had the impression from the various sceenshots and my own experience that it only works in higher altitudes. Sorry for misinterpreting. > So what I would like you to do is: > a) watch the console for any error message from shaders trying to > compile but not succeeding > b) get me a screenshot from ~20.000 ft with good visibility over land > facing the rising sun at dawn with skydome shader on and landmass shader > on > 3 > c) do the same exercise with landmass slider set to 4 Good, I will provide this this evening/ tomorrow, as I'm probably not at the computer until later evening today.
