Can we create our "own" terrain "engine" on Unity ?

Hi all,

The terrain component in Unity is inappropriate for my own project (and I find that the number of Draw Calls is very huge…).
I was wondering if we can develop our own LOD (Geoclimapping or Quad tree) + if the only class which allow us to build geometry (Mesh interface) are sufficient ?
I ask these questions because we have a very little control on the rendering pipeline and we can just manipulate buffers (vertices, indices).

Thanks in advance.

The Unity built-in terrain is mostly written with C# scripts. So, yes.

Yes you can but you’ll need to write extentions for it in C# and C++.
