A material can have multiple animations; each animation will generate a separate texture matrix, which can then be used by texgen to transform the texture coordinates accordingly. 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.

Note that despite the name, the UV animations section is meant for transforming UV coordinates in general; they don't necessarily have to be actual animations. | |||
