When using Eric Mootz's excellent emFly system, it is possible to use multiple emFly compounds.
Let's say you have a complex flight plan and you want two different landing behavours, you will need to use a unique emFly compound for each landing.
Using ICE States, you can plug in a new emFly compound into each State's 'execute once enter' and 'execute every frame'.
I haven't seen this documented anywhere, but it worked for me in Softimage 2011.
Hey, my first Softimage ICE post !
