Hi, this is my first post on the site, but I've been using the tutorial forum for a while now. Have to thank RobA for his amazing tutorial on artistic maps, it helps create such a better atmosphere to have an artsy map for my DnD players.

I have a question, which is why i'm posting here.

I'm currently mapping an entire continent in sections because not all of it is necessary and it's easier to do in sections. However a problem with this is that the northern part of the continent is snow and ice, while the southern part is not. In one particular section, there has to be a transition.

How can I seamlessly transition between land and snow? I had some thoughts about possibly using a gradient and a noise/bump map like in RobA's tutorial. But I need the texture to increase as you go northwards on the map because of snows melting rate the further south. I can only get the texture to remain consistent.

Anyone have any ideas?

Thanks in advance.
