Nexttut shows how to get displacements out of ZBrush and into Arnold in Maya.
This new tutorial from the folks at NextTut shows how you can use Zbrush’s multimap exporter to create the displacement maps you can use inside Maya using Arnold.
The workflow is pretty straightforward, but there are a few things to remember when working in ZBrush.
On a related note, you can also use Arnold in Maya to bake geometry. Check out this short walkthrough by Amar Shinde (Reimagine Fx) to show how you can bake displacement using Arnold’s Bake Selected Geometry utility.
