I'm making an airport in Lapland and it's obviously full of snow in Winter. With SODE I know that it is possible to display some objects/ground polys accoding to seasons, is it possible to do so with SAM ? I want my airport to be full of snow in Winter (with ground poly) and also my buildings to have snow on the roof (with an .obj file). If I create them and add them in my scenery can something allow me to display them ONLY in the winter and in the summer they'll be replaced by grass for example ? I'm a beginner and it's my first scenery so any help would be welcome.
