Blending Materials with Geoshells in DAZ Studio

I've made this thumbnail for a video in which I'm explaining how to use Geoshells in DAZ Studio. This is an Iray feature that lets you define a new set of material properties for an existing object. Essentially the object is rendered again with an offset, so you can blend two whole sets of shaders. I chose the DAZ Brain for this, using the "healthy" tissue shader on the main object, then applying the "rotten" tissue to the geoshell. Turning the opacity of the rotten geoshell down a notch, we can see a blend between the two, creating a "slightly rotten" brain.

I can confirm the patient is doing much better today...
