Massive Simulation - Dragon (Maya, Motionbuilder, Massive)

Quick Massive Crowd Simulation with quadruped. I bought those motion from mixamo.com, the only problem is that the skeleton (joint) isn't oriented in Y axis as primary axis and this will not work properly with Massive IK and also can make problem when using vision that require positive Z axis. I had to figure the joint orientation and re-target back the motion in Motionbuilder then export as ASF/AMC to Massive.
