Mesh rendering prob

Well, I started to work on a .x loader but there is a slight problem. I can´t get the mesh to render. I dunno is it´s just the camera or something wrong in the loading code but I would appreciate if someone could check this code out and maybe inform me on what´s wrong. First the function that loads the model bool cXEngine::GetXFile(void) { LPD3DXBUFFER lpD3DMatBuf; //Material and texture buffer if(FAILED(D3DXLoadMeshFromX("tiger.x", D3DXMESH_SYSTEMMEM, m_iD3DDev9, NULL, &lpD3DMatBuf, NULL, &m_dwNumMaterials, &m_iMesh))) { return false; } D3DXMATERIAL* d3dxMaterials = (D3DXMATERIAL*)lpD3DMatBuf->GetBufferPointer(); m_matMaterials = new D3DMATERIAL9[m_dwNumMaterials]; m_matTextures = new LPDIRECT3DTEXTURE9[m_dwNumMaterials]; for(DWORD i=0;i<m_dwNumMaterials;i++) { m_matMaterials[i] = d3dxMaterials[i].MatD3D; m_matMaterials[i].Ambient = m_matMaterials[i].Diffuse; m_matTextures[i] = NULL; // Create the texture. if( FAILED( D3DXCreateTextureFromFile( m_iD3DDev9, d3dxMaterials[i].pTextureFilename, &m_matTextures[i] ) ) ) { return false; } m_matTextures[i] = NULL; } lpD3DMatBuf->Release(); return true; } And the code that displays it void cXEngine::Render(void) { m_iD3DDev9->Clear(0, NULL, D3DCLEAR_TARGET, D3DCOLOR_XRGB(0,0,255),1.0f,0); SetupMatrices(); //Setup world,view,projection matrices m_iD3DDev9->BeginScene(); //Render the mesh for(DWORD i=1; i<m_dwNumMaterials;i++) { m_iD3DDev9->SetMaterial( &m_matMaterials[i] ); m_iD3DDev9->SetTexture( 0, m_matTextures[i] ); m_iMesh->DrawSubset( i ); } m_iD3DDev9->EndScene(); m_iD3DDev9->Present(NULL,NULL,NULL,NULL); //Present the scene, Src=bb, dest=frontb,dest win=hWnd, dirty=NULL } Oh and the camera if that´s necessary void cXEngine::SetupMatrices(void) { D3DXVECTOR3 vCamPos(0.0f, 3.0f,-5.0f); D3DXVECTOR3 vCamLookAt(0.0f, 0.0f, 0.0f); D3DXVECTOR3 vCamUpDown(0.0f, 1.0f, 0.0f); D3DXMATRIX matWorld; //World matrix m_iD3DDev9->SetTransform(D3DTS_WORLD, &matWorld); D3DXMATRIX matView; //View(camera) matrix D3DXMatrixLookAtLH(&matView, &vCamPos, &vCamLookAt, &vCamUpDown); m_iD3DDev9->SetTransform(D3DTS_VIEW, &matView); D3DXMATRIX matProj; D3DXMatrixPerspectiveFovLH(&matProj, D3DX_PI/4, 1.0f,1.0f,100.0f); m_iD3DDev9->SetTransform(D3DTS_PROJECTION, &matProj); } Bad Monkey Productions

Updated my site with the latest code. Haven´t found out what could be the source of the malfunction. It´seems to be loading the model allright and there is nothing wrong with the rendering otherwise. Please have a look at the code if you´ve got the time, I´m about to Harakiri meself.
