If one mesh is 1 billion triangles, and you have 100 different meshes, you need to store 100 billion tringles, unless you do something radically differently.
If you have 1 triangle mesh, and instance it 100 billion times, you don't need to do that.
> "more than 33 million triangles."
The assets the company they mention makes have 100s of millions of triangles, and billions as well. So I wonder if they are not using those original assets after all.
IIUC they are, but they are only rendering at lower triangle counts and the LOD happens automatically.
