All you have to do really is select the divot (where you key on the custom parameter) and drag and drop it to the "U location" divot in the constraint. This works. However, I noticed in 2014 SP2 there are no divots on the custom parameter set making it impossible to key their values in the interface... weird. It may be the particular QFE I'm using... I'll check it out. Since it may be missing, just right click on the divot of the "U Location" select 'expression editor' In the expression editor, select 'object' (on top of expression editor) >null>custParamset>custparam Apply. Now the custom param in the null will control the U Location of the other null.

Hey Eric. I got carried away with a different task. Let me get back to you on this one a little later. (I also tried your other suggestion with the = sign... didn't make a difference, if I remember correctly). I'll let you know ASAP... thanks!

I have another null on which I created a Custom Parameter, so I could drive with it the U Pos parameter on the curve constraint for the first null. I've connected them using the Parameter Connection Editor, and the constrained Null shows the following expression on its Path %age parameter: l_fcv( Rig.CustomPSet.Path_U_Pos ) However, when I go to my custom parameter on the second Null and change the value, the constrained null does not update. It does nothing. What am I missing? Thanks for any help! (P.S. I also tried getting rid of the l_fcv part of the expression, since it reads to me as if it was expecting a function curve as an input... but this didn't change anything). -- Sergio Mucino Lead Rigger Modus FX -------------------------- To unsubscribe: mail [email protected]<mailto:[email protected]> with subject "unsubscribe" and reply to the confirmation email. -- -=T=- -------------------------- To unsubscribe: mail [email protected]<mailto:[email protected]> with subject "unsubscribe" and reply to the confirmation email.
