Model got no depth? | GameDev.net

Hi guys, I'm quite new to Directx 11 and tried to load my model. However, I got a problem with its rendering. It looks like my model got no depth(look at his hands, feet, head), even though I got a depth/stencil buffer. My importer works with less complex models. Am i missing something? What could cause this? I hope you guys can help me ;)

Ty for your answer.
This is the D3dInit code(based on Frank Lunas Dx11 Book)


 bool Dx11Base::Init(HINSTANCE hInstance, HWND hwnd)
 {
 hInstance_ = hInstance;
 hwnd_ = hwnd;
 RECT dimensions;
 GetClientRect(hwnd, &dimensions);
 unsigned int width = dimensions.right - dimensions.left;
 unsigned int height = dimensions.bottom - dimensions.top;
 D3D_DRIVER_TYPE driverTypes[] =
 {
 D3D_DRIVER_TYPE_HARDWARE, D3D_DRIVER_TYPE_WARP,
 D3D_DRIVER_TYPE_SOFTWARE, D3D_DRIVER_TYPE_REFERENCE,
 };
 unsigned int totalDriverTypes = ARRAYSIZE(driverTypes);
 D3D_FEATURE_LEVEL featureLevels[] =
 {
 D3D_FEATURE_LEVEL_11_0,
 D3D_FEATURE_LEVEL_10_1,
 D3D_FEATURE_LEVEL_10_0
 };
 unsigned int totalFeatureLevels = ARRAYSIZE(featureLevels);
 DXGI_SWAP_CHAIN_DESC swapChainDesc;
 ZeroMemory(&swapChainDesc, sizeof(swapChainDesc));
 swapChainDesc.BufferCount = 1;
 swapChainDesc.BufferDesc.Width = width;
 swapChainDesc.BufferDesc.Height = height;
 swapChainDesc.BufferDesc.Format = DXGI_FORMAT_R8G8B8A8_UNORM;
 swapChainDesc.BufferDesc.RefreshRate.Numerator = 60;
 swapChainDesc.BufferDesc.RefreshRate.Denominator = 1;
 swapChainDesc.BufferUsage = DXGI_USAGE_RENDER_TARGET_OUTPUT;
 swapChainDesc.OutputWindow = hwnd;
 swapChainDesc.Windowed = true;
 swapChainDesc.SampleDesc.Count = 1;
 swapChainDesc.SampleDesc.Quality = 0;
 unsigned int creationFlags = 0;
 #ifdef _DEBUG
 creationFlags |= D3D11_CREATE_DEVICE_DEBUG;
 #endif
 HRESULT result;
 unsigned int driver = 0;
 for(driver = 0; driver < totalDriverTypes; ++driver)
 {
 result = D3D11CreateDeviceAndSwapChain(0, driverTypes[driver], 0,
 creationFlags, featureLevels, totalFeatureLevels,
 D3D11_SDK_VERSION, &swapChainDesc, &swapChain_,
 &d3dDevice_, &featureLevel_, &d3dContext_);
 
 if(SUCCEEDED(result))
 {
 driverType_=driverTypes[driver];
 break;
 }
 }
 if(FAILED(result))
 {
 DXTRACE_MSG("Failes to create the Direct3D device!");
 return false;
 }
 ID3D11Texture2D* backBufferTexture;
 result = swapChain_->GetBuffer(0, __uuidof(ID3D11Texture2D), (LPVOID*)&backBufferTexture);
 if(FAILED(result))
 {
 DXTRACE_MSG("Failed to get the swap chain back buffer!");
 return false;
 }
 result = d3dDevice_->CreateRenderTargetView(backBufferTexture, 0, &backBufferTarget_);
 if(backBufferTexture)
 backBufferTexture->Release();
 if(FAILED(result))
 {
 DXTRACE_MSG("Failed to create the renderTargetView!");
 return false;
 }
 D3D11_TEXTURE2D_DESC depthTexDesc;
 ZeroMemory(&depthTexDesc, sizeof(depthTexDesc));
 depthTexDesc.Width = width;
 depthTexDesc.Height = height;
 depthTexDesc.MipLevels = 1;
 depthTexDesc.ArraySize = 1;
 depthTexDesc.Format = DXGI_FORMAT_D24_UNORM_S8_UINT;
 depthTexDesc.SampleDesc.Count = 1;
 depthTexDesc.SampleDesc.Quality = 0;
 depthTexDesc.Usage = D3D11_USAGE_DEFAULT;
 depthTexDesc.BindFlags = D3D11_BIND_DEPTH_STENCIL;
 depthTexDesc.CPUAccessFlags = 0;
 depthTexDesc.MiscFlags = 0;
 result = d3dDevice_->CreateTexture2D(&depthTexDesc, NULL, &depthTexture_);
 if(FAILED(result))
 {
 DXTRACE_MSG("Failed to create the depth texture!");
 return false;
 }
 //depth stencil view
 D3D11_DEPTH_STENCIL_VIEW_DESC descDSV;
 ZeroMemory(&descDSV, sizeof(descDSV));
 descDSV.Format = depthTexDesc.Format;
 descDSV.ViewDimension = D3D11_DSV_DIMENSION_TEXTURE2D;
 descDSV.Texture2D.MipSlice = 0;
 result = d3dDevice_->CreateDepthStencilView(depthTexture_, &descDSV, &depthStencilView_);
 if(FAILED(result))
 {
 DXTRACE_MSG("Failed to create the depth stencil target view!");
 return false;
 }
 
 d3dContext_->OMSetRenderTargets(1, &backBufferTarget_, 0);
 D3D11_VIEWPORT viewport;
 viewport.Width = static_cast<float>(width);
 viewport.Height = static_cast<float>(height);
 viewport.MinDepth = 0.0f;
 viewport.MaxDepth = 1.0f;
 viewport.TopLeftX = 0.0f;
 viewport.TopLeftY = 0.0f;
 d3dContext_->RSSetViewports(1, &viewport);
 return LoadContent();
 }

And here is my Draw Method:


 void Modeldemo::Render()
 {
 if( d3dContext_ == 0 )
 return;
 float clearColor[4] = { 0.0f, 0.0f, 0.25f, 1.0f };
 d3dContext_->ClearRenderTargetView( backBufferTarget_, clearColor );
 d3dContext_->ClearDepthStencilView( depthStencilView_, D3D11_CLEAR_DEPTH, 1.0f, 0 );
 
 unsigned int stride = sizeof( VertexPos );
 unsigned int offset = 0;
 d3dContext_->IASetInputLayout( inputLayout_ );
 d3dContext_->IASetVertexBuffers( 0, 1, &vertexBuffer_, &stride, &offset );
 d3dContext_->IASetIndexBuffer( indexBuffer_, DXGI_FORMAT_R16_UINT, 0 );
 d3dContext_->IASetPrimitiveTopology( D3D11_PRIMITIVE_TOPOLOGY_TRIANGLELIST );
 d3dContext_->VSSetShader( colorMapVS_, 0, 0 );
 d3dContext_->PSSetShader( colorMapPS_, 0, 0 );
 d3dContext_->PSSetShaderResources( 0, 1, &colorMap_ );
 d3dContext_->PSSetSamplers( 0, 1, &colorMapSampler_ );
 XMMATRIX worldMat = XMMatrixIdentity( );
 worldMat = XMMatrixTranspose( worldMat );
 XMMATRIX viewMat = cam_.GetViewMatrix( );
 viewMat = XMMatrixTranspose( viewMat );
 d3dContext_->UpdateSubresource( worldCB_, 0, 0, &worldMat, 0, 0 );
 d3dContext_->UpdateSubresource( viewCB_, 0, 0, &viewMat, 0, 0 );
 d3dContext_->UpdateSubresource( projCB_, 0, 0, &projMatrix_, 0, 0 );
 d3dContext_->VSSetConstantBuffers( 0, 1, &worldCB_ );
 d3dContext_->VSSetConstantBuffers( 1, 1, &viewCB_ );
 d3dContext_->VSSetConstantBuffers( 2, 1, &projCB_ );
 int size = model->indicesCount;
 d3dContext_->Draw( size, 0);
 swapChain_->Present( 0, 0 );
 }

It also appears to me you have some wind-ordering issue with your model. Have you tried setting the rasterizer state to not cull back/front faces?

Yes, but no changes to the model.

Here is my ShaderCode


 Texture2D colorMap_ : register( t0 );
 SamplerState colorSampler_ : register( s0 );
 
 cbuffer cbChangesEveryFrame : register( b0 )
 {
 matrix worldMatrix;
 };
 cbuffer cbNeverChanges : register( b1 )
 {
 matrix viewMatrix;
 };
 cbuffer cbChangeOnResize : register( b2 )
 {
 matrix projMatrix;
 };
 
 struct VS_Input
 {
 float4 pos : POSITION;
 float2 tex0 : TEXCOORD0;
 };
 struct PS_Input
 {
 float4 pos : SV_POSITION;
 float2 tex0 : TEXCOORD0;
 };
 
 PS_Input VS_Main( VS_Input vertex )
 {
 PS_Input vsOut = ( PS_Input )0;
 vsOut.pos = mul( vertex.pos, worldMatrix );
 vsOut.pos = mul( vsOut.pos, viewMatrix );
 vsOut.pos = mul( vsOut.pos, projMatrix );
 vsOut.tex0 = vertex.tex0;
 return vsOut;
 }
 
 float4 PS_Main( PS_Input frag ) : SV_TARGET
 {
 return colorMap_.Sample( colorSampler_, frag.tex0 );
 }
