Got a strange errors with D3D11.
It's alwas print 'Unknown error' in output console.

After some investigations I found that error caused on this line:
https://github.com/Kode/Kore/blob/24bd154ed65ca3eb35f07eb8a53117b07903f080/Backends/Direct3D11/Sources/Kore/ProgramImpl.cpp#L240

In debug mode I got different errors on different shaders:

First type of errors:
D3D11 ERROR: ID3D11Device::CreateInputLayout: Encoded Signature size doesn't match specified size. [ STATE_CREATION ERROR #161: CREATEINPUTLAYOUT_UNPARSEABLEINPUTSIGNATURE]

Second type of errors:
D3D11 ERROR: ID3D11Device::CreateInputLayout: Element[3] and Element[2] have the same Semantic (TEXCOORD 0). All Semantics in the Input Layout must be unique. This error is only printed on the first occurence detected. [ STATE_CREATION ERROR #160: CREATEINPUTLAYOUT_DUPLICATESEMANTIC]

But everything works fine with OpenGL.

Found why second error happens.

This will work:

This will not work and will cause errors described above:

I fixed that error:
D3D11 ERROR: ID3D11Device::CreateInputLayout: Element[3] and Element[2] have the same Semantic (TEXCOORD 0). All Semantics in the Input Layout must be unique. This error is only printed on the first occurence detected. [ STATE_CREATION ERROR #160: CREATEINPUTLAYOUT_DUPLICATESEMANTIC]

By replacing COLOR with SV_Target here:
https://github.com/Kode/SPIRV-Cross/blob/64f77f45bc84033a7cbb78549d99db1422042c99/spirv_hlsl.cpp#L177

But thats will not work for D3D9, I guess.

Test project please (there have been some changes to the compiler, maybe it's already fixed).

No, I still have that errors.
Will do some research and will create a test project.

After last update this errors are gone.
Don't know what's going on and what was changed in this 18 days, but issue can be closed, I think.
Thank you.

Still here :(

@RobDangerous, try this, please. It's a sample for Kore, but it contains current issue
https://www.dropbox.com/s/q5wmevpzoesiur6/sample.zip?dl=0

I fixed something and it now runs but doesn't look much like in OpenGL. Problem is/was about unused attributes. Maybe more problems, that sample is huge...

Thanks, Robert, for all your hard work.
I can confirm that it runs now, but result is very strange :D
Here is how it looks like in my case:

Sorry for the huge sample, please, the problem became on complex shaders only so it needs normal maps and all that weird stuff.

Also, I tried to update Kore in Kha and still got this with Kha project (with crash):

So looks like I should create more complex sample with Kha :)

Nooo... I'll fix it with the Kore sample.

About:

D3D11 ERROR: ID3D11Device::CreateInputLayout: Encoded Signature size doesn't match specified size.

I found some interesting thing. With small meshes D3D works correctly. But with big meshes (like Sponza) it cause issue. But both mehses works fine with GL.

Update.
Can't reproduce ' Encoded Signature' error again...
But here is small sample that includes issue with rendering of 3D models.
GL - ok, D3D11 - not ok.

Please, check 17 line in Main.hx and try to switch LOAD_SPONZA variable from true to false for loading different models on startup.

Btw, looks like D3D9 works fine and does not contain those errors.
But there is no option to use D3D9 if you using MRT in your code or if you building to the Windows Universal app, so D3D11 is still important :)

Didn't fix your rendering yet but the actual 'Encoded Signature...' bug is fixed (Haxe/hxcpp could collect and reuse the vertex shader memory in D3D11 so it was kind of a random incident).

I get the broken output via html5 as well...

Uhm and also via OpenGL. Does this still render correctly for you?

Hey, I think it's all fixed.
