There's couple small differences you'll usually see on MREA meshes compared to CMDL ones: | ||
* Normals are ''always'' shorts, so vertex format 0 is never used. | |||
* Most MREA meshes use lightmaps, so normally the first UV coordinate on each texture will read from the short UV array. This isn't always the case, though; you need to make sure you check the material so you know where to read from. | |||
* Submeshes will usually have a bounding box in the extra data in the submesh header. This bounding box is used for depth sorting. | |||
* Each mesh starts with an extra header section which is formatted like this: | |||
