Question Inverted mask inside a scrollview

Hello,

Is there a way to have an inverted mask working inside a scrollview that also using a mask?

I have tried this

but it's not working inside an other mask.
I have also tried this https://github.com/mob-sakai/UnmaskForUGUI, but it's only reversing what it's inside the rect transform and in my use case it's not what I want.

So basically I want to have an ui element be masked normally by it's grand parent and inverse masked by it's parent.

Any idea?

 

Did you find a solution?

 

I don't remember sorry, but maybe by using this one it could work: https://github.com/mob-sakai/SoftMaskForUGUI
