While working on my Ophthalmology project I came to a point where I needed to do some radial material. In particular for the Iris but also for other tissues of the eye. The different material combiners and turbulences available did not allow to warp the material in a radial way. So I took the A:M plugin SDK and programmed my own set of material warpers. The iris image below is the result of the use of my Anular Turbulence used in different combinations.
The plugins are available for download here. RadialTurb warp the material around a specified radius in 3D space. A value less than 1.0 expands the material and a value greater than 1.0 compresses the material. AnularTurb warp the material between a small radius and a large radius. Values less then 0.0 expand the material and values greater than 0.0 compresses the material

NOTE: I release those plugins for free use but I don't pretend that they are easy to use. They have been developed for a very specific purpose and produce very localized warp in 3D space. A lot of experimentation is required to use them properly. Nevertheless, they can produce stunning results. To help you start, I provided a small project file that produces the above Iris.
