Quote - Which list would be shorter, things it can control or things it can't control?

More to the point can a prop/figure/part movement control colour or texture change?

You can control almost any node in the material room from a prop/figure/part at least since Poser 5...
A little easier using dependend parameters in Poser 7...
I don't think you can control across props/figures... Maybe it's possible with Poser 8... 

Yesterday's the past, tomorrow's the future, but today is a gift. That's why it's called the present.
