new uGUI mask doesn't work for some android devices.

I had a masking problem in the U3D editor when platform was switched to android.
Now I did a reimport all and this fixed the issue.
U3D 4.6.1

 

Will also point out: if your 'droid won't render anything at all, make sure the UI shaders are in the 'always included shaders' list. (The previous problem I had above turned out to be this dumb mistake! )

 

Updated to latest Unity 4.6.2f1 and problem still occur on Samsung Galaxy Ace 2 Android 2.3 (24-bit is checked). Content that should be hidden by mask are visible. Are there any alternatives to mask for scrolling?

 

I came across this issue. Where none of my UI objects that were a child of a mash would render.
Enabling the main camera fixed it, so thanks to Yury Habets #30 for that.

 

Even in Unity5 Add the camera it will work... Thanks again Yury..

 

I wasn't sure what you ment by that. I changed the setting "Clear Flags" on my camera from "Don't clear" to "Depth only" that solved my problem, so I guess that's probably what you ment. Thanks!

 

Hm,
on Nabi DreamTab I am seeing UGUI masks basically not having any effect.
Using 5.1.2f1.
I haven't tried 5.2.1 p2 because it introduces some other issues which I'd rather fix in our next release cycle.
I have a camera in the scene set to clear "solid color".

update:
Have now repro'd this issue with 5.2.1p2 as well,
using an extremely simple test scene.
If you want to try it, it's here on hockey.

update:
2DRectMask seems to work correctly on our problem device.

 

I'm having this issue using Clear Flags: Skybox on the main camera.

Using 2DRectMask solved the problem.

Thanks elenzil.

 

Have problems with mask UI , Mask works in Scene View , but doesn't in Game View. Unity 5.3.4.p5, Mac OS, Android Platform . Look at the attachments.

UPD:
Wow, after switching platforms to PC, WebGL, iOS and then back to Android, problem is disappear. Mask works fine .

 

does unityUI use a cached Atlas for all* masks for a scene?

 

Sometimes, the weirdest things fix the most complex issues. Didn't expect to read a triple-platform change fix today.

 

No, there is Image component with default config, without any sprite.

 

Same problem under 5.4.0f1 Android, UI Masks in world space simply does not work.

 

Yeah also on HTC m8 builded with 5.5.0f3

 

I still have the same issue on android with Mask with Unity 2018.1.0f2 Its been years and still no fix. Mask2D works

 

me too
