I am building an open world for a static camera shot. Near the camera, the terrain has high res, and in the background it's low res (cannot use high res for the entire terrain or I will run out of memory). I use the "terrain tiles" node to split the terrain into 3 tiles (near, middle, far). After processing each tile I convert each to a mesh.
My challange is when I display all meshes together they don't match at the borders. One solution is to overlap borders and upres, fuse points & average heights, etc...! Are there any better options? I am feeling I am reinventing the wheel here (maybe my workflow is completely wrong)?
Note: the reason behind the differences are things like mask blurs/expand, noise distortion that break at the border, plus each terrain might have different features (e.g only near camera there are puddles), so I cannot run the same nodes on each terrain uniformly ...
