This mode is used to scroll both U and V at the same time. It has four float parameters: ''offsetA'', ''offsetB'', ''scaleA'', and ''scaleB''. | This mode is used to scroll both U and V at the same time. It will only generate a texture matrix.

These modes can be used to scroll U and V independently from each other; they can also be used to have more advanced . The same calculation is done for both modes, with the only difference being whether the calculated offset is applied to U or V. There are four float parameters: ''scale'', ''numFrames'', ''step'', and ''offset''. | These modes can be used to scroll U and V independently from each other; they can also be used to have more advanced .

The animation is made up of a number of pseudo-frames, where ''step'' controls the amount that the texture scrolls by each frame, and ''numFrames'' sets how many frames are iterated through before resetting back to 0. ''scale'' roughly controls animation playback speed, and ''offset'' modifies the time input value. | The animation is made up of a number of pseudo-frames, where ''step'' controls the amount that the texture scrolls by each frame, and ''numFrames'' sets how many frames are iterated through before resetting back to 0.
