My shader code is having an error with returns at lines 50 and 60.
Shader "PeerPlay/NewImageEffectShader"

Properties

_MainTex ("Texture", 2D) = "white" {}
}
SubShader

// No culling or depth

half index = v.vertex.z;
v.vertex.z = 0;
o.vertex = UnityObjectToClipPos(v.vertex);
o.uv = v.uv;
o.ray = _CamFrustum[(int)index].xyz;
o.ray /= abs(o.ray.z);
o.ray = mul(_CamToWorld, o.ray)
return o;
};
fixed4 frag (v2f i) : SV_Target
{
float3 rayDirection = normalize(i.ray.xyz);
float3 rayOrigin = _CamWorldSpace;
return fixed4(rayDirection, 1);
};
ENDCG
}
}
}
At line 35;
float3 ray : TEXTCOORD1;
should be;
float3 ray : TEXCOORD1;
The returns are still not working even after the fix.
There's also two problems with line 48;
o.ray = mul(_CamToWorld, o.ray)
You're missing a semi-colon and the matrix multiplication is between incompatible types (float4x4 and float3).
