Large scale surface with high grounds and canals
Hi guys, I'm building a large scale region and rebuilding an old town. My major problem is the surface of the area, that need a lot of megabyte (more or less 800Mb...).
This is because I built the surface with a lot of faces and modified it by moving vertices with affect region option active.
I need a solution that don't use so much memory!
So I thought to use displacement map, but it's very hard to draw a large geographic grayscale map and correctly shade it: is there a software or a technique to draw and shade it easily?
Another way could be cut the surface with "loop, cut and slide" tool, and then by appling the modifier subdivision surface, but the geometry of surface don't help me so much, so it's hard draw the right way of water channels, cut them in mutiple right ways and then drag the cuts in the right position...
So? Anyone can help me?
Thank you very much!
