I thought I would keep everyone posted on progress.
We've had a number of other projects that have delayed the plugin release. Some are relevant - like making some improvements to the DMM simulator to allow it to handle larger meshes, and others are longer-term - a cloud version of DMM.
The new plugin will have material regions too. This will let you define multiple materials on a single object. It's a feature that is available in our API -
OTOY will be adding DMM to their cloud system. This will allow anyone who is using the OTOY pipeline to simulate and render high-end destruction directly in the OTOY cloud. We are all very excited about this! More details here: http://render.otoy.com/forum/viewtopic.php?f=7&t=41634
A really great breakdown of using DMM to do a truck smashing into a diner.
