Graphics problem on Samsung Galaxy S3 mini - alpha shines through nGUI

Hello,

we have a weird problem with our first mobile game on Android
https://play.google.com/store/apps/details?id=com.unilever.CoolCubes.
One mobile phone, the Samsung Galaxy S3 mini is showing the alpha from the game camera from one shader (see below) on the nGUI camera.

I don’t have a clue what is happening only that it might have to do with the shader we are using (pasted below).

If anyone has a hunch I would be very grateful,

Thanks,

Simon


Shader “Mobile/Transparent/Vertex Color” {
Properties {
_Color (“Main Color”, Color) = (1,1,1,1)
_SpecColor (“Spec Color”, Color) = (1,1,1,0)
_Emission (“Emmisive Color”, Color) = (0,0,0,0)
_Shininess (“Shininess”, Range (0.1, 1)) = 0.7
_MainTex (“Base (RGB) Trans (A)”, 2D) = “white” {}
}

Category {
Tags {“Queue”=“Transparent” “IgnoreProjector”=“True” “RenderType”=“Transparent”}
ZWrite Off
Alphatest Greater 0
Blend SrcAlpha OneMinusSrcAlpha
SubShader {
Material {
Diffuse [_Color]
Ambient [_Color]
Shininess [_Shininess]
Specular [_SpecColor]
Emission [_Emission]
}
Pass {
ColorMaterial AmbientAndDiffuse
Fog { Mode Off }
Lighting Off
SeparateSpecular On
SetTexture [_MainTex] {
Combine texture * primary, texture * primary
}
SetTexture [_MainTex] {
constantColor [_Color]
Combine previous * constant DOUBLE, previous * constant
}
}
}
}
}

I forgot to mention that you can’t see the problem on a screenshot (left), only on the photo (right).

Bizarr.

I don’t know what causes this problem, but since the ui seems to be opaque and the alpha shown is from something in the background would it be a feasible workaround to just switch off the camera that renders the stuff in the background as long as you ui is shown?

it would work in this case- but we sometimes have the 3d scene visible below the gui…

hi cubaschi!
How did you fix it? I have the similar problem (but with dynamic fonts) on S3-mini. I installed your app and it works correct on my S3-mini.
