Starting in MP2, surfaces in world geometry are now merged together to create as few meshes as possible (meshes are now only split when the vertex count exceeds 65535). Two extra data sections are present to manage the resulting super-meshes to enable the game to extract smaller meshes out when needed. | ||
This first section assigns a group ID to each surface, forming smaller meshes. This ID is used in various places that operate on world geometry, including in the [[AROT (MREA Section)|area octree]] as well as in the [[EGMC (File Format)|EGMC format]], among others. | This first section assigns a group ID to each surface, forming smaller meshes.
