| I think so. You'd need to use an effect that allows you set blending modes, and then use sampleImage() to detect when the layers overlap and then set the effect properly. Take a look at http://www.motionscript.com/design-guide/collision.html It would probably run pretty slow. If expressions run too slow AE will sometimes turn them off without telling you! -louai On Thu, Sep 6, 2012 at 2:28 PM, Teddy Gage <teddygage@gmail.com> wrote: > How would I go about creating a "conditional" blending layer?
