CMDL (Donkey Kong Country Returns): Difference between revisions

{{research|moderate|Where to begin? Materials need a lot of research (they're very similar if not the same as Metroid Prime 3). A lot of the visibility group data is unknown. The submesh headers contain a lot of unknowns, and the possible vertex format settings are unknown. Geometry should be split off into a separate article if it's confirmed that it's the same format that's used in MREA (which is fairly likely). Materials should also be split off once more is known about them.}}

There's not much known about the material format currently; DKCR seems to use the same material format as Metroid Prime 3. The main difference in DKCR compared to Prime 3 is that in Prime 3, each material set would get its own section. In DKCR, every material set is in the same section. Each material set begins with a material count, and each material begins with its own size. The main thing that's needed to read geometry is the vertex attribute flags, which are located at 0xC in the material structure (not counting the size).
