	These flags are generally toggled in pairs, with each pair corresponding to a vertex attribute; if a pair is set, then vertices using this material will have the corresponding attribute. This is vital for reading geometry. Starting in Echoes, each pair is used to indicate the size of the attribute indices in the geometry data, with 3 meaning a 16-bit index and 2 meaning an 8-bit index.

(This isn't actually used, though; the original game data always uses 16-bit indices.)

	GX supports up to 8 texture coords per vertex, but the game doesn't seem to allow you to assign more than 7 (though this could do with some double-checking).

UV Animations

@@ Line 643: / Line 643: @@
 === UV Animations ===
 The UV animations section immediately follows the texgen flags. Its purpose is to generate texture matrices and post-transform matrices, which are then used to transform UV coordinates. This is commonly used to animate textures via simple UV scrolls, but it's also often used to simulate reflective surfaces that move with the camera. Materials can have multiple UV animations; in that case, each animation generates a separate texture/post-transform matrix and are loaded into GX sequentially. Texgen is used to set which matrices are used by which UV coordinates (if any).

-The structure of the animations themselves is somewhat simple. Each animation has a 32-bit ''mode'' setting, followed by a number of float parameters. The number and usage of these float parameters varies depending on what mode is set. There are 8 possible modes.
+For info on how to read the animation data and how each animation mode works, see [[UV Animations]].

			==== Group Index ====

			The group index marks groups of materials that all have the same settings, but different textures. The game will check the value after loading the textures (but prior to the vertex attribute flags), and check whether the group index set on the material matches the material currently set up. If it does, it will skip the rest of the material setup. The value typically starts at 0 on the first material and increments by 1 on each new group with different settings.
