My brain is actually exacuating steam through my ears... I fear the overrun shortly. Please can someone help me by explaining how to reverse a scale tracking? That would be amazing. Thank you J Has someone found out since Xmas 2007? :)

I’m still stuck on that expression (yeah I’m a bit late, sorry). My brain is actually exacuating steam through my ears… I fear the overrun shortly.

Is it even needed if you check the scale box as well as the position and rotation boxes and reverse scale it, or does it have to be checked along with the expression? Do you have to pickwhip it first and then add the rest of the expression? I am little confused about the scale expression.

What exactly WAS your long-winded expression? Could it possibly rescue me?

I thought I finally had it cracked when I discovered that I could restore my original resolution by selecting 'Collapse Transformations' on the precomp's Layer Switches. However... whilst this seems to retain the tracking data for, I suppose, MOST purposes, it just doesn't seem to work in conjunction with the Liquifier effect. I can happily add in sunglasses, tinfoil hats -- stick a parrot onto my subject's shoulder, and give her an eyepatch and a wooden leg -- and as long as those layers are parented to the precomp they will follow the tracking data perfectly! But as soon as I try to apply the Liquifier with the 'Transformations Collapsed' switch selected (thus restoring my original resolution), this effect will not follow the tracking data at all... I have also tried selecting 'Preserve resolution when nested' from the Advanced Compositions Settings window -- no luck there either... Any suggestions? Andrew? Anyone? Could it perhaps be that the (reverse scale) expression needs to be modified so that it uses as its source the entire original COMP (and all of its info and properties), as opposed to just the one layer? If this sounds stupid, bear in mind that when typing expressions, I feel as though I'm reading aloud from a foreign-language phrasebook, rather than speaking a language that I actually understand ("My hovercraft is full of eels...") I hope I haven't scared everyone away from this thread... Surely I'm not the ONLY person who's been staring at their computers all weekend! Cheers...
