Wow, that just makes me want to see more..
I have made a movie showing what its basically all about. So I have taken RobA's progressive detail world maps which show how you might get the basic forms in at world scale. Then lower down there is Tareth and Landorl's maps to shoe mid range detail. Then I took Hapimeses city and Simonutp's tower to show smaller scale stuff and then I added some more tokens at human scale.
That's pretty much what I'm hoping to do, but I'll be aiming for no seams. If I do all the detail in VD, I'm thinking that it'll work out. Can you see any problems created by doing something like his city in all VD icons instead of an imported image? I'll just need to create an invisible parent to place them on, correct?
