Xcalibur

Is there a way to upgrade...I am asking because I notice there is an "updates" section http://www.hash.com/support/updates.asp or is it a matter of purchassing the newer version?... Also side tracking a bit I am trying to get two bones to rotate (say X axis) but in opposite directions (say for opening and closing an eyelid). I know the "rolll like" constraint can accept -ve scaling, is there someting like that for "orient like" constraint? Cheers

I an trying to do a 50%/50% CP weigh for the first time and I have looked at clips showing how its done....the problem is the "Edit CP weights" menu never appears I've tried it in modelling muscle(under an action) and skeletal and yet nothing.... ANY ONE CAN HELP ME ... BTW I have A:M 10.5
