I was busy with a outline shader. I'll just post the whole thing below, but this is the line that causes the crash

 

color.rgb = lerp( color.rgb, g_vLineColor, edge );

 

MODES

{

    Default();

    Forward();

}

COMMON

{

    #include "postprocess/shared.hlsl"

}

struct VertexInput

{

    float3 vPositionOs : POSITION < Semantic( PosXyz ); >;

    float2 vTexCoord : TEXCOORD0 < Semantic( LowPrecisionUv ); >;

};

struct PixelInput

{

    float2 uv : TEXCOORD0;

    #if ( PROGRAM == VFX_PROGRAM_VS )

        float4 vPositionPs : SV_Position;

    #endif

    #if ( PROGRAM == VFX_PROGRAM_PS )

        float4 vPositionSs : SV_Position;

    #endif

};

VS

{

    PixelInput MainVs( VertexInput i )

    {

        PixelInput o;

        o.vPositionPs = float4( i.vPositionOs.xy, 0.0f, 1.0f );

        o.uv = i.vTexCoord;

        return o;

    }

}

PS

{

    #include "postprocess/common.hlsl"

    #include "common/classes/Normals.hlsl"

    Texture2D g_tColorBuffer < Attribute( "ColorBuffer" ); SrgbRead( true ); >;

    float g_flLineWidth < Attribute("LineWidth"); Default(1.0); > ;

    float g_flNormalThreshold < Attribute("NormalThreshold"); Default(0.3); > ;

    float3 g_vLineColor < Attribute("LineColor"); Default3(0.05, 0.03, 0.08); > ;

    float4 MainPs( PixelInput i ) : SV_Target0

    {

        float2 uv = CalculateViewportUv( i.vPositionSs.xy );

        float4 color = g_tColorBuffer.Sample( g_sBilinearMirror, uv );

        float2 pixel = i.vPositionSs.xy - g_vViewportOffset.xy;

        float w = g_flLineWidth;

        float3 n = Normals::Sample(pixel);

        float3 nl = Normals::Sample(pixel + float2(-w, 0));

        float3 nr = Normals::Sample(pixel + float2(w, 0));

        float3 nd = Normals::Sample(pixel + float2(0, -w));

        float3 nu = Normals::Sample(pixel + float2(0, w));

        float turn = (1.0 - dot(n, nl)) + (1.0 - dot(n, nr))

           + (1.0 - dot(n, nd)) + (1.0 - dot(n, nu));

        float edge = smoothstep(g_flNormalThreshold, g_flNormalThreshold * 2.0, turn);

       
        color.rgb = lerp( color.rgb, g_vLineColor, edge );

        return color;

    }

}

 

Here is the c# code I had to apply the post process effect. 

    public sealed class ToonPost : BasePostProcess<ToonPost>
    {
        static Material Shader = Material.FromShader( "shaders/toonpost.shader" );

        public override void Render()
        {
            var blit = BlitMode.WithBackbuffer( Shader, Stage.AfterPostProcess, 100, false );
            Blit( blit, "ToonPost" );
        }
    }

I removed the Normals::Sample() and that seems to have fixed it for me. Best guess is the normal data gets lost at that stage of the pipeline or something

I keep getting this error. This time it's on another completely separate project. I'll update this as soon as I can figure out what's crashing it
