It's nice to meet you all.
I'm Kayleigh, a crowdfunded writer, and I'm looking to learn more about mapmaking here, especially using CC3, as I purchased that recently. I write in many different worlds, so I'd like to have maps for all of them, and I'd like some help from cartographers who know more than I do about where to start and how to make things look relatively realistic.
All of my writing can be found at kajoneswriting.co.uk, if anyone is interested.
Here is the first part of a good video tutorial for CC3: http://www.youtube.com/watch?v=QLaTKOJC6og
Welcome to the Guild Kajones! I know that there are some older CC3 tutorials here, but I've never used the program myself and so don't know if they have become outmoded yet or not. Given that, I'd follow Mateus's suggestion as he is a CC3 user.
