Unity UI Shader that hides what is behind it.

Does anyone have a UI shader that essentially cuts a hole in the UI? I tried the DepthMask shader from the wiki with no luck. Everything behind the image would be invisible revealing the camera that is behind.

 

You can achieve that through various means, wither using a RestMask2D with the appropriate image.
Or alternatively use the Soft Alpha Mask UI component in the Unity UI Extensions project (link in signature) which can use alpha masking to mask an image.

hope that helps.

 

I don't believe a Mask can achieve this effect. To clarify, I am having my Camera's viewport rect conform to a RectTransform as if it were an image itself. This is why I would like my camera to essentially block the UI controls that are behind it.

 

@SimonDarksideJ Could you tell me how to do it the Soft Alpha Mask UI way? I couldn't find the proper tutorial on how to use that script. I wanted to do something like what I posted in this forum:

I am trying to achieve this exact same effect. Been googling but can't find anything. Anyone got any ideas?

 

With 3D objects the DepthMask shader does exactly this. For some reason it just doesn't work w/ the UI system.

 

Sadly, I specifically need it to work with the UI, actually, probably only on the UI. My use case it actually exactly the same as yours was. Camera's render position and size is set by a rectTransform, and I want to remove all the UI within that rect.
