Pixelux has updated its DMM Plug-In to be included in Maya 2012. The version included with Maya has no limitations on features, but is limited to 1500 simulation elements (tets). All previous owners of the DMM Plug-In can enable the simulation of unlimited numbers of tets simply by re-installing their license. New users wishing to utilize unlimited numbers of simulation elements can purchase the plug-in on our online store for only USD $299.
(Update) - We will be updating the free version of the plug-in to support 2500 elements shortly. This version will also contains some bug-fixes as well as performance improvements for the Linux and OS X versions.
