 TURBULENCE rotates a linked texture around randomly placed warping points. You can
control the size and density of the "warping regions", which can overlap and interfere with one another. TURBULENCE deforms in three dimensions.
How Does It Work?
The Density parameter sets the number of warping regions in a given area. The warping regions are
organized into sets. If Density is set to 0.0, there won't be any warping regions, but as the Density increases a set of warping regions will appear and begin to expand. Once a set of warping regions
reaches maximum size, they'll cease to grow and a new set of regions will appear. The regions reach maximum size at specific densities (0.0, 10.0, 20.0, etc.).
The Distortion parameter sets the amount of distortion (rotation) as a percent of the maximum (which is controlled by the Scale Factor parameter). You can link Distortion to a Generator to define a distortion profile, otherwise it will be linear. The Generator defines the amount of distortion from the outside edge of
the warping region to the center. Whatever Generator Distortion is linked to will combine with the internal linear profile. This ensures that the distortion at the outermost edge of the region will be 0.0 and won't
cause any discontinuities.
Hints!
TURBULENCE, along with Warp is excellent for breaking up patterns and making textures more organic- looking.
The warping regions of TURBULENCE line up with the warping regions of the Warp component, as long
as both have the same densities.
Note: Higher Turbulence and Density values significantly decrease texture speed.
