I've pushed some updates to Advanced Weather and the cloud shader of Atmospheric Light Scattering.
Clouds now fade to transparent at distances between the visibility and 3 times the visibility. This gives a much better impression when in heavy groud fog (CAT I to CAT III) and shouldn't be a problem above the cloud layer for semi-realistic visibilities (if you have 20 km, you get clouds drawn out to 60 km or so). CAT IIIb using Atmospheric Light Scattering and Advanced Weather should now give better results (I won't start thinking how to support Basic Weather properly before this actually works) - although it takes a while for the system to ramp down the visibility to very low values (the interpolation routine has a time delay) - you may have to wait for 20 seconds till the visibility is actually all the way down. However, the change does mean that if you leave the visibility at cruise altitudes of airliners at 10 km, you will not get to see many clouds regardless of how the cloud visibility range is set (because they now respect the real visibility setting in addition), so this is potentially an issue for Basic Weather users. If this is a show-stopper, then we may need to undo the changes, but fading to alpha is by far the fastest way to deal with heavily fogged clouds. Please test and give feedback! Runway lighting and the sun are still not okay and seen through fog - any pointers as to where to modify the lights are highly appreciated. I've also tinkered a bit with the thunderstorm scenario and reduced the density of clouds surrounding the Cb towers as well as the number of sprites being used - I now get quite acceptable framerates of ~20-30 fps in the scenario - maybe it also helps for others. One problemhere is that rain textures are still orphaned (i.e. don't move in the wind with the clouds) - I'm running out of ideas here - my Nasal moving code creates frame spacing issues, Vivian's C++ moving code patch wasn't accepted, so I'd appreciate a helping hand from C++ coders before the next release. * Thorsten ------------------------------------------------------------------------------ Everyone hates slow websites.
