Unity 4.6 Mask not working in iOS

The new Mask component is not working on iOS. It is working correctly in preview mode when running on Mac or Windows, but when deployed to an actual iOS device (iPad 3rd gen, in my case) the mask is completely ignored and the children of the mask object are rendered even outside the mask.

I am on 4.6 beta 17.

Is this a bug, or am I missing something?

 

I believe that you have to tick "Use 24-bit Depth Buffer" in Player Settings > Resolution and Presentation. I'm not really sure why though.

 

Thanks, hamstar. Worked like a charm.

 

Still not working for me. I'm loading a JPG into a Raw Image component that is being masked at runtime. It acts as though the mask simply isn't there.

 

I had a similar issue in the unity editor and after switching to another platform and back it worked for me.

 

Hmm. No dice for me. Thanks for the suggestion though Marcel71.

 

Just to be clear .jpg's don't have alpha channels. (may not be apparent to everyone)

 

Ah I see. That makes sense. I'll look into this. Hopefully I can add an alpha channel to the image at runtime, as it's a JPG loaded off a web server. The mask I'm using is a PNG with alpha channel. But I guess what you're saying is that the masked image also needs an alpha channel that the mask will be applied to?

 

I guess I can use the following:

No dice. I've started a separate thread.

 

I've got this same problem, but I'm using .psd files, all with full alpha (they're borders and semi-transparent background fills and what not).

Could there be another reason the masks do not work?

 

Are you running the latest beta? The issue resolved itself for me in b20.

 

b19. I've downlaoded b20 but it broke some stuff with a plugin (InControl) that I have to use, so I figured I'd let that developer have a bit more time before pestering them for another 4.6 update Fortunately the game still works just fine w/o the mask, it just looks better with it. So I'll keep on keeping on.
Thanks!

 

b20. I had the same issue with the mask not working on iOS and by ticking "Use 24-bit Depth Buffer" in Player Settings > Resolution and Presentation, it fixed my problem (thanks hamstar). To Unity folks, please add this info in your documentation.

 

b19 having the 24-bit depth buffer checked also worked for me. (Both of the boxes are checked)

 

I still have this issue on iOS (8.1) with Unity 4.6p1. Also 24-bit depth buffer checked worked for me.

 

go to build settings -> other settings -> device filter
and select ARM v7
worked for me....
