Terrain and layer graphs

San Van’s ground uses Frostbite TerrainData with 36 layers and a cooked layer-graph virtual texture. Its 5,492 measured terrain decals belong to this native terrain system, separately from mesh decal materials and environment decal volumes. Observed

Terrain/compositor parameter depots can use <asset>.layergraphs_shaderblockdepot names and the same depot container as level materials. The measured depot samples reproduce byte for byte, but that does not establish the terrain graph or virtual-texture page layout. Observed

Studio’s mesh-based surface materials do not provide an established authoring route for stock TerrainData. Replacing a ground surface with a mesh is therefore a different representation from the native terrain system. Observed

How are the terrain graph and virtual-texture pages encoded?

Layer count and cooked-system identity are measured; the complete graph, page tables and blend evaluation are not decoded here. Unknown
