View Full Version : Track Matte Question

05 May 2010, 04:47 PM
Is there a way to use the "TrkMat" feature so that the layer you're referencing doesn't have to be above the layer it's applied to?

Not that i'm aware of, but some creative pre-composing can help solve any issues that might crop up from having to do that. What problem are you running into with the layer order?

from the "Set Matte" section of After Effects Help (
"The layer used as the matte with the Set Matte effect can be anywhere in the layer stacking order, unlike a track matte layer, which must be directly above the matted layer in the layer stacking order."

Iaenic: I managed to use Precomping with a few expressions to get what I wanted. Wish there were an easier way.

ToddKopriva: Set Mattes are referenced as a stationary effect. I'm looking for independent motion regarding both sources.

A Track Matte Effect would be ideal. If at all possible.

Effect --> Distort --> Transform, rigged with expressions to mimic your reference layer's motion. All you need. No need to reinvent the wheel. Know your tools!
