I come here with a bit of a question, I'm prepping to start working on an environment in UDK and the basis of it will be centered around an island. To be specific its the "Old town" island in Stockholm. I've read up and learned about how to create and sculpt the landscapes, how to import heightmaps etc etc. But what I'm a bit stuck at is planning up the right size to go with.
So, here's a rough picture of the island layout from the era the environment will be set in:
I've calculated that I'd need a map which creates a landscape which is roughly 2000 square feet. But digging through the documentation most of the landscape maps are sized like 4033x4033, 2017x2017, 1009x1009 etc. And that doesnt really say "how large they are" or what their corresponding unit size is. Does anyone know a good way to calculate this? Because I'd want to get as close to true size with the island as possible. Or would you advice me to take another approach?
