Done with metar enabled And the last CVS update Do i have missed anything ? here the progress climbing from sealevel to 8000 ft we may notice some strange behaviour One/ the transparency, does the alpha sorted correctly ? http://pagesperso-orange.fr/GRTux/3DClouds-img10.jpg Two/ Here everything is right, however some little flickering http://pagesperso-orange.fr/GRTux/3DClouds-img11.jpg Three/ Nothing wrong we are in a "fog" layer view from above http://pagesperso-orange.fr/GRTux/3DClouds-img12.jpg Four/ the same than previous but view from under ??? only a ghost no "fog" ! http://pagesperso-orange.fr/GRTux/3DClouds-img13.jpg Five/ at a higher altitude leaving the "fog", suddenly the clouds layer under vanish partly, like a mask which move above, then we get with transparency the sea. We should have a full layer of clouds again an alpha order problem http://pagesperso-orange.fr/GRTux/3DClouds-img14.jpg I experimented it several time, with several Airborn, and the same result :( Everything with Cloud density 1 and visibility range 20000 Cheers -- Gérard http://pagesperso-orange.fr/GRTux/ J'ai décidé d'être heureux parce que c'est bon pour la santé.
