How do I add masks to multiple objects in a single clip?

Hello, I’m a beginner with kdenlive. I want to know how to mask multiple objects in the same clip adding different effects to each mask. I try to and only the effects of the first mask are used.

nvm I feel like an idiot now. I needed to copy across tracks lmao.

You can do that with (mask) > effect > Mask Apply > (mask) > effect > Mask Apply > … in one clip. You have to change the way the mask works (Min vs Max, Screen vs Write on, and so on).
