See the screenshot below. This is pretty dark, obviously, but I Think you can see the issue in the landing lights of the (great) L-39. In short, it looks like an impressionistic painting. This is the ground near Orbx's Cessnock airport, which certainly does not look like this during the daytime. It also happens anywhere, so the issue is not with this particular scenery or the ground textures.In the next shot I have adjusted the brightness of a view of the sky in Photoshop to show the color banding issues in the night sky.I have my video card set to 32-bit, and everything looks awesome (no color banding, true-to-life colors) dawn, daylight and dusk. At night, it turns into a horrid mess.I've searched the forums and have seen the issue come up a couple of times, but the responses were usually "make sure you are 32-bit" and there never seemed to be any resolution.I'm really enjoying night flying with the (great) L-39 and would love to get this sorted out. Any ideas?Card is Nvidia 8800GTS-512. Latest drivers. All older drivers uninstalled and cleaned with Driver Sweeper.

Are you running REX and if so, did you check the box to replace the landing light textures? That would overwrite the L-39 landing lights and could be your problem. In any case, you could try simply re-installing the L-39 and seeing if overwriting all the files makes a difference. Make sure you have the lastest L-39 version before re-installing.Another possibility is the HDR mod. This has an option for increasing colour saturation at night (and during the day as well). If you are running the HDR mod check the settings in the enbseries.ini file.Cheers,Noel.

Hi Jimmy. That issue with the landing lights is mostly unavoidable, it's just how FSX shades things at night. The ambient light is quite low, so any colour data in the ground (except grey runways) will end up getting amplified a bit and produce a kaleidoscopic effect sometimes, mostly over brownish ground. This can also be made better or worse by aftermarket sky textures, which have some control over the lighting built into them. You'll notice this side effect mostly on a new moon as well, on a full moon it looks a lot nicer, again because of the higher ambient light level.To increase the brightness at night you can try messing with these two lines in your FSX.cfg (you'll have to add them). It may reduce that issue a bit.In the [GRAPHICS] section of the file:DAY_THRESHOLD=32768NIGHT_THRESHOLD=4096Those values are default, so you can play with them and see if it improves anything. Bumping up the night threshold value should increase the ambient light level at night.As for the banding in the sky, you'll never get rid of it, unless you own a CRT monitor. LCD screens (99% of them anyway) are not true 24 bit, they're 18 bit, only capable of displaying around 230,000 colours. So the darker things get the more of that banding you will see.It makes me miss my old CRT, except for the weight, hehe. Until better monitor technologies come along we're kind stuck with that. There are LCD screens capable of displaying true 24 bit colour, but their pixel refresh is so slow that they're all but useless for anything but Photoshop work. They're also quite expensive.Hope that helps.-Mike (aka lotus)

Mike: that helps a lot, thank you. I thought it was something specific to my system. I guess it's been a general issue, but I only really noticed when the L-39 put the spotlight on it, so to speak.I had also darkened the night a bit via the enbseries plug-in, so I imagine that is probably exacerbating the effect.The L-39 is the best add-on aircraft I've ever seen for MSFS, BTW, bar none. I really hope it's a success for you.
