  • Apply one effect (stroke or fill) to some of multiple masks

    Posted by Marie Bauni on April 15, 2025 at 11:16 pm

    I have 150 masks on a Solid Layer, I applied a Fill effect, but instead of duplicating this effect 150 times and add as much keyframes to control each mask.

    I would like to create a slider control, that can control on which mask the effect is applied ? Is there any possibility to do that ? So I can go from 1 to 150, and choose the good mask.

    Then I would like to expend that choice, and select 3 masks at a time, from 1-3, then 2-4, etc. With the same process ?

    I think maybe with some expressions with the Index or something, but I can’t find it.

    Thank you 🙂
