Dammit... have to reinstall my After effect, and all my plugins.
my serial stoped working today.. mabye my timemachine can help !?
lets try..
didn work.. argh, have to get my copy of CS3 ad work then...(hmmm CS4 might miss you, CS5 is just around the corner).
back to bussines...
if (thisComp.layer("Null 1").effect("checkbox control")("Checkbox")==0)Opacity=0
if (thisComp.layer("Null 1").effect("checkbox control")("Checkbox")==1)Opacity=100
so.. there is a checkbox effect on layer "null 1" and it controles the opacity.
and i belive you also can use > < instead of = in the if expression.
i better try this out tommorow. (and get som spell cheking on this as well.. lol)
