We have just posted a customer story covering some of Asylum's work on Terminator Salvation using Houdini.
Given the detail needed to set up a realistic robot, Houdini was used for both the rigging and animation. Asylum chose Houdini because of its digital asset pipeline which would allow several different people to work on the same rig at the same time making it easier to bring all the parts together for final output.
