shader compilation fails #11

Open Mathias-Fuchs opened 5 years ago

Mathias-Fuchs commented 5 years ago

Hello! I can build the getting started sample fine, using the nuget version 4.5.0 of velgrid, but .net core host seems to crash during the spirv shader compilation: 

$ dotnet run

Unhandled Exception: SharpDX.SharpDXException: HRESULT: [0x80070057], Module: [General], ApiCode: [E_INVALIDARG/Invalid Arguments], Message: Falscher Parameter.

   at GettingStarted.Program.Main(String[] args) in C:\Users\Dell\source\repos\K3D_Mesher\MF\Visualizer2\main.cs:line 59

This happens in the line

            _shaders = factory.CreateFromSpirv(vertexShaderDesc, fragmentShaderDesc);

Any help appreciated! MF

Have you made any modifications to the example code? I'm able to run the GettingStarted project under D3D11 without the above problem. The error indicates that the VertexLayoutDescription might have been modified from what is in the repo -- is that the case?

Hello mellinoe, thanks for answer. No, I can't seem to find any difference. It alsow works on Linux. The vertex layout is still

VertexLayoutDescription vertexLayout = new VertexLayoutDescription(
                new VertexElementDescription("Position", VertexElementSemantic.TextureCoordinate, VertexElementFormat.Float2),
                new VertexElementDescription("Color", VertexElementSemantic.TextureCoordinate, VertexElementFormat.Float4)
                );

and the class VertexLayoutDescription hasn't changed either.

Any new thoughts on this issue? It keeps nagging me ....

yep. Same here... could it be the reason if i have DirectX12 not 11 under windows 10?
