Hiya,
Another shader question. I’ve had this shader sitting in my library for a while now and just started using it, I wish I remember who i got it from because it’s fantastic.But I have one problem. I assume it’s rendering this object first and then putting everything else in front because if there is nothing visibly behind it you can see it. Otherwise it’s hidden. I can’t figure out how to fix it.
Shader "HaloLightning" {
Properties {
_NoiseTex("Noise (RGBA)", 2D) = "white" {}
_Noise("Noise", FLOAT) = 0.2
_Speed("Speed", FLOAT) = 0.2
_FallOff("FallOff", FLOAT) = 2
_Lines("Lines", FLOAT) = 0.2
_Color("Tint Color", COLOR) = (0.5,0.5,0.5,0.5)
_Width("Width", FLOAT) = 0.2
_camDir("Camera Look Direction", Vector) = (1,0,0,0)
}

o.position = mul(UNITY_MATRIX_MVP, v.vertex + float4(v.normal, 0) * _Width);
o.uv = TRANSFORM_TEX(v.texcoord, _NoiseTex);
o.viewAngle = 1- abs(dot(v.normal, normalize(_camDir.xyz)));
o.ypos = o.position.y;
return o;
}
half4 frag(v2f i) : COLOR{
float2 uvOffset1 = _Time.xy*_Noise;
float2 uvOffset2 = -_Time.xx*_Noise;
half4 noise1 = tex2D(_NoiseTex, i.uv + uvOffset1);
half4 noise2 = tex2D(_NoiseTex, i.uv + uvOffset2);
float noise = (dot(noise1, noise2) - 1) * _Noise;
half4 col = sin((i.ypos*_Lines + _Time.x*_Speed + noise)*100);
noise1 = tex2D(_NoiseTex, i.uv*6 + uvOffset1);
noise2 = tex2D(_NoiseTex, i.uv*6 + uvOffset2);
col.a *= saturate(1.3-(noise1.g+noise2.g)) * pow(i.viewAngle,_FallOff) * 15;
return col * _Color * 2;
}
ENDCG

Thanks for any help
