I'm working in a composition in which I have created a form in plexus. I then want to use the form as a track matte with some footage. I have the footage as a 3d layer behind the Plexus form so that when I move the camera, it moves along with it etc. When I move the camera sometimes the form will change perspective but not the footage...
And the sometimes the plexus form goes haywire and glitches... anyone have a problem like this?
Make sure you purge the disk cache (or disable it). There are cases when the disk cache does not update properly and shows expired frames. This would make it appear as if it was a glitch. This is an After Effects issue so please report it to Adobe here: http://adobe.com/go/wish
