Exporting Alpha Channel
Hello all,
I have an RGB precomp that I want to place in the alpha channel for output to Silhouette. It’s a matte layer which will be overtop of the RGB image. I can’t seem to remember how to do this..
Any help would be greatly appreciated!!
Thanks,

Change the track matte of the RGB layer to “Alpha Matte” or if it’s just a black and white layer to “Luma Matte”. F4 toggles between the switches and track mattes.

Hey John,
Thanks for the quick response! I was actually forgetting that I needed a straight alpha for the output.
Thanks!
