We used to have 45 km range out to which clouds were shown. With the new more efficient system, I have made tests with 75 km (which is enough for a good impression even from airliner cruise altitude), see here: http://www.phy.duke.edu/~trenk/pics/local-weather-next05.jpg The penalty for having this is not so severe as compared with other goodies (it's cheaper than the terrain haze for instance). Technically, tile generation is tied to actual visibility. The max. visibility the system generates at high altitude is 140 km or a user-specified maximum, whichever is lower, so cloud positions are computed at most out to 80 km or so. Clouds are shown out to the same distance as normal 3d clouds since they are subject to the same distance slider. If you hard-code some lower number for the release, please let me know where to change it so that I can go back to my extended layer testing. * Thorsten ------------------------------------------------------------------------------ Ridiculously easy VDI.
