to win a licence would be cool but not really the main motorvator for me..i guess if sidefx dont plan a new apprentice challenge we could do our own, but i dont really think that it would be so appropiate to have an unofficial challenge at the sidefx forum (unless a mod thinks its a good idea) perhaps if we spoke to the nice folks at odforce they may start up a thread for it…guess it depends how many people would be interested…

thanks for the responces….i tried using the fit() expression on the translation of a sphere to drive another sphere twice the distance and it all went swimmingly….however with more complex relationships it is a bit of a hardship to write expressions for each..as you say it would be nice to have a connection editor UI of some sort….

i dont quite understand how to achieve the same thing in CHOPs yet, you guys have said that both expression channels and CHOPs are cached..so would there be any more advantage or overhead saving to be had in using CHOPs to drive this kind of relationship…

thanks again

thanks for the reply…youve not missed the point at all…i think i need to look a little deeper into CHOPs….

what i want is when an object (such as a bone) reaches a certain angle (or position) for it to drive some other animated paramiter…when building rigs in maya this stuff is invaluable…and indeed im sure there are several ways to achieve this in houdini…i shall take a look at the docs again and come back if i am still a little astray…

thanks..
