I am a new Unity user and am attempting to model a real-world scene. The area I would like to model is large (3500 m x 3500 m). I have a 16-bit grayscale image to use for the large scale detail such as hills and river valley.
My problem is that there are a couple of areas in the middle of the terrain that I need to model in high detail (say 0.5 m resolution) These features include ditches, sand piles, small ponds and irrigation canals. Since the highest height map resolution allowed is 2049, I don’t think that I can do this with a single terrain.
Any suggestions for solving this problem? I understand there is a script for connecting multiple terrains. Would this work? Does it allow for melding terrains of different resolutions and sizes? When you use it, does the resulting terrain become limited to the maximum height map resolution of 2049?
