Rendering Zbrush displacements with Renderman for Maya.

Hey everyone here's another video I made for all you Zbrush users who have had a tough time figuring out how to take all the sculpted details back to maya.In this tutorial I have explained both the Zbrush and Maya parts, so everything from exporting the displacements with the displacement exporter 3 in Zbrush to setting up the maya scene and shader network to render using renderman 2.0.Why am I using Renderman for this?why not mental ray?well because renderman is a Reyes renderer(http://en.wikipedia.org/wiki/Reyes_rendering)so displacements are blazing fast to render using Renderman.That dosen't mean you cannot render displacements with mental ray,actually the mental displacements are quite good but it takes a little longer to setup and renders are surprisingly fast too,but thats a totally different story:-)
