I was trying to load a mesh from file in my DirectX 11 application.
As the base I took my own code (that renders some Primitives now) and I wanted to add to it code of mesh creating/rendering from "Basic HLSL" Project from DirectX 11 SDK Samples (which uses e.g. SDKmesh.h and DXUT.h from samples.

The mesh code is:

The mesh code is:

[source lang="cpp"] class FeyModel : public Graphic::Model, public FeyGraphicElement{ protected: CDXUTSDKMesh mesh; public: FeyModel(ID3D11Device * device, std::string filename, const Common::Point3D center){ mesh.Create( device, L"tiny\\tiny.sdkmesh", false ); //for now tiny.sdkmesh } void render(FeyShader * shader, FeyCamera * camera, ID3D11DeviceContext* context, float t ){ UINT Strides[1]; UINT Offsets[1]; ID3D11Buffer* pVB[1]; pVB[0] = mesh.GetVB11( 0, 0 ); Strides[0] = ( UINT )mesh.GetVertexStride( 0, 0 ); Offsets[0] = 0; context->IASetVertexBuffers( 0, 1, pVB, Strides, Offsets ); context->IASetIndexBuffer( mesh.GetIB11( 0 ), mesh.GetIBFormat11( 0 ), 0 ); SDKMESH_SUBSET* pSubset = NULL; D3D11_PRIMITIVE_TOPOLOGY PrimType; //! context->PSSetSamplers( 0, 1, &samLinear ); for( UINT subset = 0; subset < mesh.GetNumSubsets( 0 ); ++subset ) { // Get the subset pSubset = mesh.GetSubset( 0, subset ); PrimType = CDXUTSDKMesh::GetPrimitiveType11( ( SDKMESH_PRIMITIVE_TYPE )pSubset->PrimitiveType ); context->IASetPrimitiveTopology( PrimType ); // TODO: D3D11 - material loading ID3D11ShaderResourceView* pDiffuseRV = mesh.GetMaterial( pSubset->MaterialID )->pDiffuseRV11; context->PSSetShaderResources( 0, 1, &pDiffuseRV ); context->DrawIndexed( ( UINT )pSubset->IndexCount, 0, ( UINT )pSubset->VertexStart ); } } };[/source]

I have also noticed that in the sample, there was a different vertex layout, so I have changed my shader's class code to (the code will be executed once, in shader's class constructor, before mesh creating):


[source lang="cpp"] ... const D3D11_INPUT_ELEMENT_DESC layout[] = { { "POSITION", 0, DXGI_FORMAT_R32G32B32_FLOAT, 0, 0, D3D11_INPUT_PER_VERTEX_DATA, 0 }, { "NORMAL", 0, DXGI_FORMAT_R32G32B32_FLOAT, 0, 12, D3D11_INPUT_PER_VERTEX_DATA, 0 }, { "TEXCOORD", 0, DXGI_FORMAT_R32G32_FLOAT, 0, 24, D3D11_INPUT_PER_VERTEX_DATA, 0 }, }; UINT numElements = ARRAYSIZE( layout ); // Create the input layout hr = device->CreateInputLayout( layout, numElements, pVSBlob->GetBufferPointer(), pVSBlob->GetBufferSize(), &*vertexLayout ); pVSBlob->Release(); // Set the input layout context->IASetInputLayout( *vertexLayout ); ...[/source]

The compilation works. But during the execution of code I get error:

Access violation reading location 0x00000000

In SDKmish.h near:

[source lang="cpp"]if (bSRGB) { // This is a workaround so that we can load linearly, but sample in SRGB. Right now, we can't load // as linear since D3DX will try to do conversion on load. Loading as TYPELESS doesn't work either, and // loading as typed _UNORM doesn't allow us to create an SRGB view. // on d3d11 featuer levels this is just a copy, but on 10L9 we must use a cpu side copy with 2 staging resources.

Precisely in the line:
[source lang="cpp"] pContext->CopyResource( srgbStaging, unormStaging );[/source]


When I comment few lines of that function and something in my code (I now can't remember what line were that) I get the mesh in the window, but without textures. So I guess it's something with textures? I have the tiny model and texture in the proper folder, I have also set vertex layout like I have posted above.

What else should I do?

Please consider checking HREULT values for method Create and others.
Maybe you would pass a cannonical path instead of its short form.
