I knew rigging my Moosah and Chub model would be quite the project, but once I understood some of Softimage XSI’s rigging features it went pretty smooth. For this model I created a whole series of soft constraints, which can give the effect of secondary action, gravity, wind resistance, etc. These soft constraints will run realtime and can be used to create automated rigs. With my model, I was able to animate the beast and have the rider and accessories all react believably to just the beast’s movement.
