quick photoshop analogy to get to my question:
in photoshop, you can control the propogation of an adjustment layer located within a group by changing the default blend mode of the group from "pass through" to "normal"
is there some similar method in after effects to limit an adjustment layer's influence to only those layers within the same pre-comp?
thanks very much
No. You must precompose.
If the adjustment layer is in a precomp, it shouldn't be affectling layers outside of the precomp (unless you've selected the continuously rasterize button).
hmmm, I bet that's it;
I've used continuously rasterize for the vector assets I'm using...
