So it's more complex than doing a bit of search & replace?
Also, since the current beta, XP ties (distant) ground lighting to the ground textures. Do those distant lights show with terramaxx as well?
Is it possible to tweak the seasons? If I e.g. wanted to use Autumn ground textures for "mild winter" and mild winter ground textures for "hard winter"?
(Not only would I hope to save some precious SSD disk space by this... I would also perceive it as more realistic when winter isn't snowy at all times.)
