> btw, how do you limit (range) a result inside the mathematical patch? you need a somewhat goofy construct:
min(max(x, 0), 1) this will clamp x to be between 0 and 1. Change 0 and 1 as necessary, just make sure they're in the correct order. There are other more complex functions if you want a continuous function -- those are beyond the scope of this email, and more along the lines of a maths text book :) [such questions pop up on the list from time to time, and another would likely yield an interesting discussion] -- Christopher Wright [email protected]
