Texture2DMS isn't recognized by the slang

[bryan05]

I encounter an error:
my shader code is like this:
Texture2DMS<float4,2> s_texture_0 : register(t0);

in c++ code its kind is NULL
ReflectionType::SharedPtr reflectType(TypeLayoutReflection* pSlangType, const ReflectionPath* pPath)
{
auto kind = pSlangType->getType()->getKind();

Thanks for reporting this. I’ll look into it.

I think the issue here is that Slang does not support passing an explicit sample count to the Texture2DMS type. When I write a stand-alone shader with a declaration like:

Texture2DMS<float4, 2> gTexture;

I get an error from the Slang compiler:

test.slang(1): error 39999: too many arguments to call (got 2, expected 1)

While that error message isn't great, it is accurate because the Slang compiler only expects a single argument for the Texture2D generic type. If I rewrite my declaration as follows:

Texture2DMS<float4> gTexture;

I find that the shader compiles without error to DXBC for Shader Model 5.0, and in my stand-alone testing the reflection info I get back appears to be valid.

Can you confirm what version of Falcor you are using, and perhaps share a minimal example that reproduces the problem?

I passed slangFlags |= SLANG_COMPILE_FLAG_NO_CHECKING as the compile flag, so I don't get that error.
after passing single argument for the Texture2D generic type, I get the valid reflection info.

My version is 3.0.
thanks very much
