    Code (CSharp):
    1. #pragma kernel CSMain
    2.  
    3. RWTexture2D<float4> Result;
    4. Texture2D<float4> Gradient; SamplerState samplerGradient;
    5. Texture2D<float4> Noise; SamplerState samplerNoise;
    6. float Intensity;
    7. float2 GradientOffset;
    8. float2 NoiseOffset;
    9.  
    10. [numthreads(8,8,1)]
    11. void CSMain (uint3 dtid : SV_DispatchThreadID)
    12. {
    13.     Result[dtid.xy] = tex2D(samplerGradient, dtid.xy + GradientOffset.xy) + tex2D(samplerNoise, dtid.xy + NoiseOffset.xy)*Intensity;
    14. }
    15.  
    Very unhelpfully I get this message....

    cannot map expression to cs_5_0 instruction set

    Now I have no idea?!?

    This is a shader-themed question, which is under the graphics forum

    No problem, but you should check the forum description next time, just to make sure. This post might be moved by a moderator though
