Texture Mask working in Editor not on Devices!!

[cbothra]

Hi,

Right now I am facing a big problem. I created a texture and put a mask on it which is perfectly working in unity editor.
When I created the build and ran the same scene in Android device then I was surprised looking no masking there.

Please help me to get out of this issue.

Thanks-in-advance.

I am not sure what this has to do with NGUI... Or were you talking about the clipping mask? If so, make sure your Quality Settings aren't set to Fastest, as this disables shader support.

Hi ArenMook,

First of all I would like to thank you for taking time to reply. Here's my complete scenario:

I create a Texture and put Unlit/Transparent Masked on it. In the Unlit/Transparent Masked shader, I put a another texture as mask in the shader which is working perfect in editor but when I create the apk and run it on device the the masking is no more effective. Following is the shader I am using:

1. Shader "Unlit/Transparent Masked"
2. {
3.         Properties
4.         {
5.                 _MainTex ("Base (RGB), Alpha (A)", 2D) = "black" {}
6.                 _Mask ("Alpha (A)", 2D) = "white" {}
7.         }
8.        
9.         SubShader
10.         {
11.                 LOD 200
12.  
13.                 Tags
14.                 {
15.                         "Queue" = "Transparent"
16.                         "IgnoreProjector" = "True"
17.                         "RenderType" = "Transparent"
18.                 }
19.                
20.                 Pass
21.                 {
22.                         Cull Off
23.                         Lighting Off
24.                         ZWrite Off
25.                         Fog { Mode Off }
26.                         Offset -1, -1
27.                         Blend SrcAlpha OneMinusSrcAlpha
28.

My last advice still stands. Double-check your quality settings.

[cbothra]

I confirm that my Quality settings is not set to fastest, but still no luck with the issue.

[ArenMook]

What device is it? Does it actually support shaders? Did you ensure that the shader gets included in the build? Do other shader-based things work, such as clipped panels?

[cbothra]

What device is it?

Nexus 7

Does it actually support shaders?

Yes

Did you ensure that the shader gets included in the build?

Could you please let me know how to check that?

Do other shader-based things work, such as clipped panels?

Yes clipping is working perfectly.

[cbothra]

Hi ArenMook,

I checked the editor log and confirm that the shader is being included in the build.

[ArenMook]

Then I am out of ideas. If clipping works fine, but mask doesn't and it gets included, then it should work. If it doesn't, I wouldn't know why that is. It all works as expected on my end, but I don't have a Nexus 7.

[cbothra]

Hi ArenMook,

Could you please do me one favour? Could you please pass me the download link to your project, so that I can check on Nexus 7 by creating the build. And if it works then I can check where I am going wrong.

Thanks-in-advance.

[ArenMook]

What project? The examples that come with NGUI? You already have them.

[cbothra]

Not the projects that comes with NGUI package but the one which you can create which just contains this masking stuff and I will compile it here for android and run on device.

[ArenMook]

0. New scene.
1. ALT+SHIFT+T to add a texture and choose one.
2. Select the sprite, right-click, Create -> Scroll View.
3. Drag & drop the texture to be a child of this scroll view.
4. Select the scroll view object and on its UIPanel change Clipping to be Texture Mask and choose any texture with alpha in it.

That's all I do. But sure, I've attached the scene that takes the steps above. Tested & works properly on my Asus tablet.

Just curious if OP found a solution?  I am having the same issue and haven't been able to get it working on android or ios.

I have tried multiple texture import settings to no avail.

*EDIT: I actually just got one to work where the texture's only difference is that the compression is set to truecolor.  Gonna test out the others.
