[HELP] I keep getting the error "function return value is missing semantics" was created by sixstringseraph
I am trying to make a shader that renders to two textures, but I keep getting an error saying I'm missing semantics. I've looked and compared to examples but I cannot fix it. Any help would be appreciated.
texture texDS_1x1 { Width = 6; Height = 2; Format = RGBA16F; };
texture texPrevious { Width = 6; Height = 2; Format = RGBA16F; };
sampler samplerDS_1x1
{
Texture = texDS_1x1;
MipFilter = POINT;
MinFilter = POINT;
MagFilter = POINT;
};
sampler samplerPrevious
{
Texture = texPrevious;
MipFilter = POINT;
MinFilter = POINT;
MagFilter = POINT;
};
float4 PS_NightCheck( float4 pos : SV_Position, float2 texcoord : TEXCOORD, out float4 finalValue : SV_Target0, out float4 prevMin : SV_Target1 )
{
float3 minColor;
float avgBlue=0;
float avgRed=0;
float avgGrn=0;
float3 checkValue;
int2 SampleRes = 32;
for( int y = 0; y < SampleRes.y; ++y )
{
for( int x = 0; x < SampleRes.x; ++x )
{
minColor = tex2Dfetch( samplerDS_1_Min, int2( x, y )).xyz;
if (minColor.z>0.05f&&minColor.x<0.05f)
{++avgBlue;}
if (minColor.x>0.05f&&minColor.z<0.05f)
{++avgRed;}
if (minColor.y>0.05f&&minColor.z<0.05f)
{++avgGrn;}
}
}
if (avgBlue>;(avgRed+avgGrn))
{
checkValue= ( 0.0f, 0.0f, 1.0f );
}
else
{
checkValue= ( 1.0f, 0.0f, 0.0f );
}
prevMin.xyz = tex2D( samplerDS_1x1, texcoord).xyz;
if (abs(prevMin.x-checkValue.x)>0.5)
{
finalValue.xyz = prevMin.xyz ;
prevMin.xyz = checkValue.xyz ;
}
else
{
finalValue.xyz = checkValue.xyz;
}
// Return
finalValue = float4( finalValue.xyz, 1.0f ) ;
prevMin = float4( prevMin.xyz, 1.0f ) ;
}
// PASS
pass NightCheck //<-- ERROR HERE
{
VertexShader = PostProcessVS;
PixelShader = PS_NightCheck;
RenderTarget0 = texDS_1x1;
RenderTarget1 = texPrevious;
}

Your "PS_NightCheck" is declared to return a float4 ("float4 PS_NightCheck(...)"), but no semantic is attached to it (would have to be "float4 PS_NightCheck(...) : SEMANTIC").
But you are actually returning data via out parameters now (finalValue and prevMin), so the function doesn't need a return type.
So simply changing your function declaration to this should fix it:

That makes complete sense, and I never would ever have found it. Thanks so much! And thank for Reshade!
