I have a Scroll Rect with a Mask on a Canvas set to World Space, it looks fine in Editor but on my Nexus 5 the mask is not being applied. Used to work fine before 5.2 I think but I have made a few changes since last time I tested so I can't guarantee that the Unity update is what broke it.

"Use 32-bit Display Buffer" is checked, "Rendering path" is set to Forward and "Disable Depth and Stencil" is unchecked under Player Settings . The image is a Raw Image.

Any ideas?

Try re-testing with Unity 5.3, the UI system seems to have stabalised a bit and has also had it's masking components replaced with a new clipping framework.

Alternatively try the Soft Alpha UI Mask as part of the UI Extensions project (https://bitbucket.org/ddreaper/unity-ui-extensions) which is a shader based approach with alpha support.

Hope this helps

In case this is still relevant to anybody, I've tested a fix proposed here, which is to add a Camera GameObject to your scene. I'm using Unity 5.3.4f1 to make a UI only mobile game (every component is a UI component since I don't need anything more than that). Upon adding a camera to the top of the Hierarchy tree (just dropped it there at the top), the problematic mask suddenly works fine.

Hope this helps someone.

Rect Mask 2D works instead Mask.
