LOD pictures

Every LOD from the same camera, for the 3 meshes with LODs and the most triangles. Nanite meshes show their fallback mesh and its LODs.

Nanite or LODs

Estimates from each mesh's own data, not measurements on the devices. Nanite data of meshes without Nanite: about 14.4 bytes per triangle (Epic's documented average). LOD chain: GPU memory of the mesh's LODs, or of the default preset's chain when it has none.
