    Well, alrighty then.

    So, I go to photoshop and I make 2 new graphics. one zig zags and one poka dots. I make them consisting of 3 layers. A solid background, a copy of the background with the dots or zigs, and the third layer the dots or zigs on a transparent background. Ok two graphics one dots and one zig zags. I also go into channels, and with the dots or zigs selected, create an alpha channel. I save both artworks as varing amounts of layers from flattend thru the 3 layers with an alpha channel.

    I load all sorts on combinations of layers, alphas, into AE and not only that I change the interpert footage settings- i.e. ignore, straight umatted,
    and premultiplied-matted with color.

    Also, under modes I checked and unchecked the T transparency and inverted and also worked with the TrkMat.. Track Matte settings.

    I now understand why I did not have a grasp on Masks, Mattes, Alpha Channels. Billions & billions (god bless Carl Sagan) of combinations. Man talk about complexity. When a person fully has a grasp of all of the effects available along with modes “silhouette alpha” (nothing’s NORMAL) one definately gets a gold star right in the middle of his forhead.

    After ten hours today now, I at least appreciate what I am trying to understand. May the ghost of Einstien fly up my nose.

    This definately has a difficulty factor of 8 or I gotta buy the book.(Chris & Trish Meyer’s)

    Once again- I appreciate everyone’s help

    AND… Has anyone been to http://www.photo.net– It would be way cool if this site also accomodated and displayed members motion graphics artwork– I know, big task but I’m a dreamer.

    Not only that but I feel that what is going on here is a forerunner to a widely accepted artform. I know it already is an artform but “the people” don’t even know it.

    I’m assuming from your post that you can’t see any difference between the different files after importing?

    If you need your layers and transparencies intact, make sure you import the PSD as a composition. It’s an option in the import dialog that comes up.
