Hi.
I'm trying to make a simple 2-part eye in ZBrush that is basically a sphere within a sphere. The outer sphere is transparent the inner sphere is white with iris concavity. How can I control transparency, refraction and caustics on my 'Lens' shell? Am I trying to re-invent the wheel here or is there a tutorial on this? Now that we have 'Subtools', many of the available tutes don't address this.
My big problem is the corneal transparency. It always seems foggy. Do we still need to use 'Layers' to control these attributes?
Thanks!
