Laser Expression
Hi all,
I have a laser effect that I am working on for a gunfight sequence. I’ve tweaked out the laser and have it just the way I want it. Not I need to comp it into the footage. The problem is that the laser effect takes place within multiply nested compositions, the final effect living in a master top comp…. the basic shape and vector space (X,Y and rotation) is done via Trapcode 3D stroke. In comping this laser back into the footage I basically have to create 100s of duplicates of the laser master… position them, etc. I attempted to make an adjustment layer, with expression controls that would control the perameters of the 3D stroke, but that adjustment layer only works in the bottom nested comp of the laser effect… Does anyone have any ideas of how to make an expression control layer that would fit on top of or in the master laser effect layer? Oh and Big props to Andrew Kramer for his Action Movie Essentials pack!

You can have control layers in whatever comp you desire. Just point your effects to it using comp(“X”).layer(“Y”).effect(“Laser Control”)(“Slider”) instead of doing the same with thisComp().

I keep trying that expression and I keep and getting an error message. Any thoughts as to why?

I figured it out… I had imported the laser effect project into the current project I was working in, in addition the laser effect was made up of pre-comps upon pre-comps… I think that those two things in tandem made the expression ‘freak-out’… I rebuild the effect, with freshly named comps and now the expression works perfectly.

What is the exact expression you are using and what is the error message you are getting?

The effect sounds intriguing, certainly different from other beam effects we’ve contemplated around here. Maybe you could put up a clip someplace where we could see it?
