Neato.
I mainly cobble maps together in GIMP. I only played around with the early versions of CC ages ago, and Dundjinni a little after.
Can you import textures and such into CC? If so, do you know about the CSUAC? I have no idea what the acronym stands for anymore, but it’s a huge honkin’ collection of textures, objects and such gathered for mapping.
Also, the Cartographer’s Guild? Really helpful forum of mappers on pretty much every platform. There are a lot of helpful folks and tutorials there as well as insanely cool maps.
