Hi Gerad and Stuart, First I will comment the pics shown here:

The clouds are rather dense here- maybe too dense so it could be maybe solved with better cloud definition by xml and textures. > > > Two/ > > > Here everything is right, however some little > flickering > > > > http://pagesperso-orange.fr/GRTux/3DClouds-img11.jpg Flickering -o.k. I can live with that. I noticed the same issue on the MSFS x-Demo with their clouds. But it seems that they interpolate the color and alpha values of the sprites which makes the clouds soft and maybe prevent this visible sorting we still have. And well- MSFS has money and a lot more people working on the clouds than we have! (X-pLane has these flickerings too- you can notice on a video on youtube) If I can see right- you have a fps of 26- that's rather high- how you did this? With this clouds I have around 6fps- and I have usually about 60fps. > > > > Four/ > > > the same than previous but view from under ??? > only a ghost no "fog" ! > > > > http://pagesperso-orange.fr/GRTux/3DClouds-img13.jpg Looks strange- what's that for a cloud layer above?

In the moment I don't see that we can get this with 3d-clouds and from the commercial (game)sims I know, that they even use 2d-layers instead. So we should use the 2d-layers instead. Maybe we can improve the textures for these 2d-clouds. Generelly the clouds appearence is better though of course we should add some alpha to the textures. I will try this to make this weekend. Maybe I can try to give the clouds a bit more volume- just changing the xml-config! The only thing I don't like, that is that the cloud visibility range is only to 20km and at the horizon they look very blueish- never seen in reality. Changing the weather needs a long time now - some seconds until the new weather is loaded.
