Numbers greater than 1 will increase the size, fractions less than 1 will decrease the size, and negative numbers flip the texture. Continually scrolls the texture in both the S and T directions, or scrolls according to the function definition. Negative numbers scroll in the opposite direction. Use fractional values for very slow movement. Continually rotates the texture, or rotates according to the function definition.
Negative numbers change rotation direction.
Use fractional values for very slow movement. The first number following the command specifies the amount of warping, the second affects how quickly the turbulence is animated, and the optional phase value offsets the animation's timing for asynchronos motion. For best results, the surface should be subdivided. To avoid the 'Hall of Mirrors' artifact along warped edges, surfaces with a geometry modified base layer should not block vis. The engine only considers the original vertex coordinates for collision detection and depth sorting so caution must be exercised to avoid rendering anomolies.
