New support for Vector Displacement Maps (VDMs) in FBX 2012, lets you transfer complex high-resolution details created in Mudbox 2012 to other applications for rendering on low-resolution geometry.
VDMs can represent directional displacements that do not simply follow the normal: for example, forms with appendages, undercuts, folds, and bulges, such as a human ear; support for rendering VDMs is now included with Maya 2012, 3ds Max 2012, and Softimage 2012.
