You're welcome. That shader is fun to use on other things as well.

The parameters are:

PM:Pyramids (vertically) - how many pyramids per unit of V texture coordinate.

PM:Aspect Ratio (H/W) - the ratio of height versus width of the pyramid in UV space. For spheres you want it near 2. I noticed in the real photo that they were not square, so I used 2.2.

PM:Pyramid Height (inch) - how far the peak sticks out, in inches

PM:Bias (Curves faces) - .5 is neutral and makes flat sides. Values above .5 (up to 1) will bow the sides outward. Values below .5 (down to 0) will curve the sides inward towards the base.

Here I applied it to Andy using:

Pyramids=20

Aspect Ratio = 2

Height = 1

Bias = .25
