The material animations section immediately follows the texgen flags. It starts with this short header: | |||

|} | |||
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 7 possible modes, but only 2-5 are known. | |||
For all of the following modes, let ''s'' be equal to ''seconds mod 900''. | |||
==== Mode 2: UV Offset ==== | |||
This mode is used to scroll both U and V at the same time. It has four float parameters: ''offsetA'', ''offsetB'', ''scaleA'', and ''scaleB''. | |||
<pre>uOffset = (s * scaleA) + offsetA; | |||
vOffset = (s * scaleB) + offsetB;</pre> | |||
==== Mode 3: Rotation ==== | |||
This mode rotates the material. It has two float parameters: ''offset'' and ''scale''. | |||
<pre>angle = (s * scale) + offset;</pre> | |||
The material is then rotated by ''angle'' degrees. | |||
==== Mode 4/5: U/V Offset ==== | |||
This mode can be used to scroll U and V independently from each other. It has four float parameters. The offset calculation for these modes is unknown; however, the same code is used for both modes, with the only difference being whether the calculated offset is applied to U or V. | |||
