I am trying to develop a RTS game that has:
Each planet topology could vary between chock full of craters, to smooth hills and mountains planets
In sum each "biome" should be unique-ish (try to reusable textures/objects)
I'd like to achieve an appearance similar to Mars Battle, with its usual terrain with craters and rocks, smoothly transitioning to giant features like this detailed crater:
What I've already know/tried in my tests of terrain:
Unity terrain - it does the job for the small gravel and rocks but for example the finest detail of ridges on the crater edges is not achievable. The amount of mesh detail is not enough, makes blurry.
2D tilesets - I have experimented in the past with 2D tilesets and read some articles about how Starcraft II uses some hacks to give the impression of relief while only being a 2D image, but still this is so seamless!
2D tilesets for terrain, meshes for crater - could be a mix? In that case my doubts are the seamlessless between terrain and crater mesh. And also how can there be constructable buildings inside the crater if is a mesh?
How can I achieve something like this?
