Trying to extend GetVertexData (DX11.GeomFX) by TexCoord1...

Hi evvvverybody,
after four years i'm giving it another try:
Tampering meshes with two UV-sets in DX11 including reading/writing to disk. I hope we can figure this ut this time.
I started adapting GetVertexData and it's geometry shaders, but obviously the expansion does not work as expected.
Link to a new forum thread might follow ;)

This is the adaption of the geometryShader for UV1:

RWStructuredBuffer<float2> RWValueBuffer : BACKBUFFER;
ByteAddressBuffer vData;
uint buffersize;
 
[numthreads(256,1,1)]
void CS(uint3 dtid : SV_DispatchThreadID)
{
    if (dtid.x > buffersize) { return; }
    RWValueBuffer[dtid.x] = float2(asfloat(vData.Load(dtid.x * 40 + 32)),asfloat(vData.Load(dtid.x * 40 + 36)));
}
 
 
 
 
technique11 UV1
{
    pass P0
    {
        SetComputeShader( CompileShader( cs_5_0, CS() ) );
    }
}

See the hard-wired stride size of 40? I changed this from 32 for all four shaders but somehow i doubt that is correct.
