Tweaking haze colour and clouds?

[JimmiG 244]

Hi.I've been trying out the commented and modified flt3.cfg file available here on AVSim. It contains a couple of nice presets and explains how you can modify the haze yourself.However I'm not 100% happy with the haze and clouds. With the default .cfg, the clouds and sky looks pretty good. One problem is that the sky tends to be a little bit too bright (almost white) when flying low but it's not such a big deal. The haze looks good, but it's a bit too yellow.With the modified cfg file, the haze looks a bit deeper and more "real", but it's too redish. Also, the clouds turned white?!Basically, what I want is a more realistic haze color. Something a bit more on the grey-blue side, instead of the default yellowish haze, and I want to make the sky a bit darker when flying low.How should I tweak the values to achieve that?

Jimmy,See my Screenshots posted in FU3 and Screenshots forums. I use the commented cfg file as well. White clouds? My Nvidia card made mincemeat of 'em until I changed the haze method to 'multipass' from 'specular'. There is a note about 'black clouds' in the original cfg file - this DOES seem to affect some cards. Basically, you get black clouds during the day and white ones at night :-grrOther than that, I have tweaked a couple of settings here and there - some of it to remove the excess redness from clouds (reduced red and added blue by same small amounts) in most of my haze settings. I DID try some large changes but got GREEN haze :~P I now find that I never need more than 50% haze to totally blot out the horizon!Maybe Rob D or another person more knowledgeable can give you more exact information? I am quite happy with my current settings as-is now. If you would like a copy, please let me know :-)Catch ya,Jon Point*************************(effyouthree@hotmail.com)*************************

Would you mind posting a screenshot showing what it looks like during daytime, with some clouds, and medium haze? I'll post a shot showing my problem soon. The clouds are too white during the day as well so I don't know what the problem is. Only one type of cloud turns white, the smaller, puffy ones. The bigger ones look OK.I have one week off from school so I finally got some time to tinker with flightsims. All those maths and physics tests were killing me.Now I've got one whole week for doing more important stuff, like sitting in front of the computer, playing flightsims :-lol

Don't laugh Jimmi.........you are absolutely right :-)Chris Low,ENGLAND.

Here's a screenshot showing the problem. All those clouds are have no detail at all, they're all white. Is it meant to look like this with the tweaked cfg file?

Jon's right. Change your skyhaze from specular to multipass and its a whole new ball game. He's done more tweaking since I made the annotated cfg file so listen to the expert (and it ain't me).Just a few comments though:-- haze is modelled incredibly well by LGS. When you look through hazeat ground level, it is totally different to looking through haze a few thousand feet up, since air density changes (quite quickly) with altitude.-- earth's main atmosphere (troposphere?) is only about 65,000 ft,and I don't think the atmosphere attempts to model accurately above this height (so I slightly disagree with Laurie's atmosphere settings as he defines a larger atmosphere) - after this temperature may increase again. All of our weather is in this troposphere, and storm cell height is also limited by this.-- I am not sure that the sunset effect is captured well by LGS - in effect we simulate it by increasing red a little - hoping it is not noticed during the day!! - but causing a strong effect at night. This is difficult to get right because light is painted in many ways by the program - absorption, reflection, diffusion, scattering etc - so clouds might look good at some settings, and the sky go wrong.I don't think we have an absolute answer yet on the best settings - so experiment.-- Most settings will have no effect unless there is sufficient haze to scatter the light and pick up the spectrum separation. But high haze is basically smoke or mist - an effect which (correctly) obscures your view and reduces the pleasure of flying.Rob D.
