So apparently tex2D is still supported in HLSL shaderModel 6.0 so why does doing something like the following produce validation errors:

float myFloat = tex2D(MySampler, In.texCoord).w;

It does not like tex2D, if I make a Texture2D MyTex variable 1st then do MyFloat = MyTex.Sample(MySampler, In.texCoord).w; validation is fine.

Of course I have disables validation with /Vd and dxc spits out a compiled file but no .asm when specified, dxc also tends to jam up with tex2D usage....

I have tried compilation with multiple versions of dxc.exe

Any ideas?

Thanks

What validation errors? – SurvivalMachine Feb 05 '20 at 17:15
Are you building with ``/Gec`` (Enable backward compatibility mode)? – Chuck Walbourn Feb 05 '20 at 20:50
@Chuck Walbourn /Gec is depricated in 6.0 and above – Sixjac Feb 05 '20 at 21:09
@SurvivalMachine validation errors are: Never resolved value found in function Validation failed. It complains about tex2D always – Sixjac Feb 06 '20 at 10:17
