How to render faster Displacement Mapping
(by Jean-Sebastien Perron)

-The "Bump Height" of the material should be equal to the "Max Displacement" of the object properties.
-"Material Bump Height" = "Object Max Displacement"
-Displacement is 100 times faster on SDS objects than on Nurbs objects.
-Use small values for the displacement.
-Grey means no displacement, black will dig in the surface while white will rise from the surface.
