    Hello. I’d really appreciate if anyone could tell me what’s going wrong here. I’ll try to explain as simply as I can:

    I have 2 comps. One is two animated shape layers. The other is a looping paper texture.

    I want to confine this paper texture to my shape layers (so it looks like the shape is made of paper) but the two methods I would normally use aren’t working.

    1. Setting the texture comp to preserve underlying transparency and setting it to multiple causes very noticeable white and jaggy edges.

    2. Setting the shape layer comp to luma matte removes the white jaggy edges, but it makes the shape layers semi transparent.

    Please if you could help at all that’d be great. Been bashing my head against this for hours.

    And you can’t use an Alpha Matte in the track matte settings? And if you can’t what about the Set Matte effect?

    Thanks for the reply. This is what I get when I use Alpha Matte – it’s not the kind of affect I’m looking for. I went the paper to have the same gradient. When using alpha matte I can’t lower the opacity of the texture to get some of the colour back through because the entire shape dissapears.

    Set matte produces the same jagged white lines that look even worse when added into Premiere.

    There’s go to be a simple way to do this. All I’m after is a looping texture on a shape :/

    If you use Alpha Matte as your track matte, instead of lower it’s opacity, leave it turned off, but duplicate it, and control the copy’s opacity

    Sorry, I’ve been stuck at a conference all week, so this is my first chance to reply.

    Would you be prepared to post the project? I can take a look and see if I can spot a solution.
