How to draw on top of a shader applied to camera

Unity Engine
1

Hello,

I got a shader applied directly to the camera (used for Fog of War). I would like some object shader to be able to draw themself on top of that shader.

I’m a bit new to shader programmation. I tried messing with ZTest/ZWrite and “Queue” tag but nothing allowed my shader to render on top of that Camera/Fow shader : /

My FoW shader use:

SubShader
{
    Pass
    {
        ZTest Always
        Cull Off
        ZWrite Off
        Fog { Mode off }
        CGPROGRAM
            frag/vert function blabla
        ENDCG
    }
}

My object shader use:

SubShader
{
    Tags{ "Queue" = "Overlay+1" }
    Pass
    {
        ZTest Always
        Cull Off
        ZWrite Off
        Fog { Mode off }
        CGPROGRAM
            frag/vert function blabla
        ENDCG
    }
}

Disabling [ZTest Always], [Cull Off], [ZWrite Off] or [Fog { Mode off }] on the FoW shader didn’t helped, the object shader is still invisible

Any idea, input ? (Would be greatly appreciated =^) )

You did not specify what are you actually trying to draw, but couldn’t you just use a different camera and set it to the correct priority so that it is drawn on top?

You could try using another camera.
