It's actually... pretty complicated to address that properly. Early snow in fall would have the mountain-tops covered, and the deciduous trees down in the valley would often be bright orange-red whereas the higher trees would start being dull brown. Later in the year, all deciduous trees regardless of altitude would be leafless, but in mixed forest the needle trees (on the same texture sheet) would remain green. In early spring, you can have no snow, but still leafless trees. So a plausible model for trees in different seasons requires the ability * to distinguish needle and deciduous trees on the same texture sheet (we're probably going to do that by using the index number) * to color-rotate the deciduous trees from green via yellow to red, dull brown and finally transparent based on the selected season and altitude Note that trees usually evolve according to season, not according to snow cover, so we really need a season slider to simulate that properly - it doesn't do to just remove leaves from snow-covered trees and keep trees below the snowline in bright green. I have made some progress with an autumn-color model for the terrain which can probably be extended to spring http://www.flightgear.org/forums/viewtopic.php?f=47&t=18580 and there are some ideas both by Stuart and Emilian how to tackle the trees, but it still requires a bit of R&D to make this work. I would think that we have continuous season model by the next release which includes trees. > So at least for now we need at least some winter textures and the > ability to select to select them. Well, one could drop the terrain winter textures and keep the tree winter textures and just make trees selectable - that would also allow to access autumn tree texture sheets which currently isn't done. But for the proper solution, see above. * Thorsten ------------------------------------------------------------------------------ Everyone hates slow websites. So do we.
