There are a host of dynamic engines currently available in Maya including the original Maya dynamics, the Nucleus system, PhysX, DMM and Bullet and each one has it's own qualities that are beneficial to specific areas of games or visual effects, this can be confusing to say the least but I suppose that Autodesk, in having so many choices, have got a very flexible tool in Maya which can only be a good thing in industry.
Anyway, ramble over, here's my first test using the DMM Cinematic plug-in from Maya 2012. Hopefully I will have time this weekend to continue my investigation of it....
