it's just me or grabpass is broken

Unity Engine

Hello.
I’m doing basic heat shader for android and actually done it but stumbled upon grabpass not working when reaching some camera distance.
I’ve simplified shader code to minimum but the bug still appears.
Here’s the shader:

Shader "Custom/Example" {
    Properties {
        _Color ("Color", Color) = (1,1,1,1)
    }
    SubShader {
        GrabPass { }
        Pass
        {
            SetTexture [_GrabTexture]
        }
    }
    FallBack "Diffuse"
}

As you can see whenever I zoom in/out in editor the box texture appears or disappears and same thing happens in camera view!
Does anybody have a clue about what’s happening?
PS Unity 5.1.1f1 (64-bit)

oh snap, adding queue tag to subshader section fixes this problem… thanks.

Tags {
    "Queue" = "Geometry+1"
}

You got grabpass to work? I found it returned the last set texutre rather than everything else for me. :smile:

EDIT: I mean’t the issue on android, BTW… :wink:
