I was using Silhouette Alpha to make the layer turn black. I then imported in a new illustrator file to the composition and it completely messed up the alpha channels in the comp I was working in and I couldn't get it to go back to black. Instead they appeared transparant.
Can any body tell me how to get the Silhouette Alpha to turn it black instead of see through please or if there is another work around I can use to make the contents of the layer turn black that would be really helpful.
Problem solved. It needed to be in a composition that had a background image for the silhouette alpha to pick information up from. If it had a transparent back ground there was no information which is why it showed up as transparent.
