          Inquestflash: You would have to Pre-Compose the layer with CC Snow, before applying the Mask to the resulting Pre-Comp.

           

          So, it would  be as follows:

           

          1. Apply the CC Snow effect to the layer you want.

          2. With just that layer selected, go to Layer > Pre-Compose (Command + Shift + C on Mac, Control + **** + C on Windows).

          3. In the Pre-Compose dialog, make sure you select the second option ("Move all attributes into the new Composition").

          4. Draw the circular Mask on the resulting Pre-Comp.

           

          The reason why we're doing this is processing order: If you go right now and twirl open the layer with CC Snow in the timeline, you'll see property groups in this order: Masks,  Effects, Transform. This means that, for each frame, AE  applies masks first, then effects and then transform properties. The Mask can't restrict CC Snow because it's applied before the effect. By Pre-Composing, you're forcing everything inside the Pre-Comp to be processed before everything applied outside (For example, a Mask you add to the Pre-Comp).

              Evidently, I made a mistake when typing the name of the shift key

              Thanks for the wishes. Same to you.

                hello adoldo!

                 

                one more question if u dont mind,all is working well with the masking of the

                cc snow,but!!!since im making a crystal ball with a x-mass tree in it,id

                like for the cc snow mask to be transperant with no background,because its

                overlaping the x-mass tree.so is it possible for the cc snow to be masked in

                a circle but with no background?so image your making a snow crystal globe:

                how wold to make the snow not over lapping the x-mass tree.

                 

                thank you again.
