I guess you learned at school that there are 4 seasons in each year. But when you start making scenery for Flight Simulator you will see that FS actually has 5 seasons. Besides the usual seasons spring, summer, autumn and winter, FS also has a heavy winter season. This means winter with snow actually.
So in the ground polygon wizard of ModelConverterX you could define these 5 seasons before. But today I have added an extra season, which I called winter2. This allows you to have a “normal” winter without snow before and after the heavy winter season. For those of you making scenery of more northern areas that will be useful I think.
So there you have it, the ground polygon wizard now has 6 seasons available for you.
