I've spent the last 2 weeks researching how the best animators on YouTube make their maps and think I've found the answers, I hope they help others.
I've always wanted to know how popular animators made their video but was stuck at the first hurdle of understanding the maps they used.
This is just what I think these creators use, some of them may not be correct i.e. Invicta but the others I'm fairly sure are.
