Embedded Masks?

For masks to be very useful they need to work as children of objects that already have a mask. So i can create a button with its own mask and have it inside a panel that also has a mask.

Currently only the parent-most mask will take effect. Which aside from being confusing and unexpected, makes prefabs using masks unpredictable - depending on the where your prefab is placed in the hierarchy it might get completely broken by a parent mask.

Here's a use case i thought i could solve with masks. I have a large texture that contains scratches and tarnish that i want to use across multiple UI elements and have it apply nicely on top of sprite sliced tile/stretch behavior. I thought, simply drop the scratches image on my button, move it around for a random seed and have a mask on the button clip off all the excess.

Instead to solve this i used Multiple materials on uGUI/Unlit/Detail with the scratches set to Detail channel and different offsets for each material. Then use PositionAsUV1 on the button to apply the scratches - but this approach is convoluted, unnatural and comes with its own downsides.

Masks also need to have blended edges.

 

Case 62988

 

It seems that unity only accepts two nested masks for what I've tried. Is it the expected behaviour?

 

Having the same issue.

 

Same issue here, seems to be a regression from Beta, where nested masks worked at mutliple levels on hierachy.(more than 2 levels)

Any ETA on when this may be looked at (have a deadline of mid Jan) - and want to know if I should look at other workaround for a series of scroll list windows.
