XGen Arbitrary Primitive Generator
With the extension for Maya 2014, you get access to the XGen Arbitrary Primitive Generator technology used by Walt Disney Animation Studios in the hit animated films Tangled, and Bolt, and by Pixar Animation Studios in Toy Story 3.  XGen enables you to generate curves, spheres, and custom geometry on the surface of polygon meshes in order to create and groom hair, fur, and feathers on characters, and quickly populate large landscapes with grass, foliage, trees, rocks, and debris trails. With geometry created procedurally at render time, XGen enables you to handle large amounts of instanced data that would slow down a system if loaded in memory. The rendered effect can be previewed interactively in the Maya Viewport 2.0 hardware-accelerated display; you can control the appearance and behavior of the primitives by setting attributes, painting maps, creating expressions, or using the included XGroom interactive grooming toolset; long hair can be controlled by creating guide hairs, which can be simulated using the Maya nHair toolset.

New Retopology Toolset
The NEX modeling technology first integrated in Autodesk Maya 2014 software has been further extended to offer a streamlined workflow for retopologizing meshes; the Quad Draw tool now integrates a new Relax and Tweak feature with Soft Selection, and a new interactive Edge Extend tool. You can now optimize your meshes for cleaner deformations and better performance from a single toolset within Maya.

Better Booleans
Maya now employs a robust and efficient new library for faster and more reliable Boolean operations on polygon geometry. The new technology has been extensively tested and optimized on a number of complex high-resolution datasets, and delivers dependable results on open surfaces.

Bullet Physics Enhancements
The Extension for Maya 2014 delivers several enhancements to the Bullet plug-in that enables you to use the open source Bullet physics engine to create large-scale, highly realistic dynamic and kinematic simulations within Maya. Delivered in conjunction with AMD (Advanced Micro Devices), the Bullet plug-in now offers the ability to create compound collision shapes from multiple meshes; produces better collisions with concave shapes, thanks to a new Hierarchical Approximate Convex Decomposition (HACD) algorithm; integrates with Maya Forces; and support rigid sets for increased scalability.
