I am working on a new iris shadow option for my procedural material CW Eye for Blender.
The new shadow gives you the ability to simulate a kind of iris depth. Using this shadow the eye gets a look that reminds of characters created by Pixar Animation Studios.
The release is not final yet because I am working on some additional features for the shadow, like rotation e.g. Procedural rotations are always a bit tricky, so I need some more time.
As soon as the new version is published all CW Eye customers will get the update for free of course, as always.
