How can I optimize a very large terrain mesh?
My mesh is 6000x6000 vertices. In my game, you can zoom out all the way to see the entire map, and rotate camera in all directions. Because of this, I cannot use lod on nearby and far away tiles. The only lod I can use is on the entire map as you zoom out. But as you zoom in, the entire map must keep the same lod.
So how is it possible to optimize this?
Divide this big mesh into a set of smaller ones. With separate AABBs this alone will open up options for occlusion and LODs. 10x10 or 30x30 should be enough to make a difference.
Downside of this path is that you need to figure out how to resolve seams between terrain chunks.
