Yeah, I think the title already describes what I am asking for. It would be nice, that when its getting cold and snow starts to fall, the trees would actually have snow on them too. We already have changing tree texture for leaf based trees, but not pines, etc. And for someone who mostly plays in the colder parts of the rimworlds, this would be a great little mod.
So if someone has the skills to make one, I would be very happy.
