Hi Jeff

My bad for assuming that they had actually changed the functionality.

The picture above (SR4.1 again) is a reproduction of some of the ones that I put in the beta forum thread.

The ball on the left is a standard Poser ball with a noise node attached to the displacement channel and Displaceemnt value 5. Rendered using the scanline Reyes algorithms.

On the left is that same prop reflected in a mirror using Firefly's raytracer. The effect is due to the fact the mesh vertices are being displaced in an attampt to emulate the scanline displacement.

Unfortunately as the mesh density is much lower than the detail in the noise pattern, the effect is the random clumpiness.

Bear in mind that the displacement algorithms were really developed by Pixar to enhance surface texturing, not to create modelling detail. It is a bonus that in scanline rendering displacement can be used to enhance geometry, but (not to look a gift horse in the mouth) this unexpected bonus only goes so far.
