Вопрос чайника — пытаюсь отрисовать кубик руководствуясь примером compress из sdk,
слегка его изменив чтобы можно было натянуть отдельную текстуру на каждую грань.

Создание vertex'ов:
#define NUM_CUBE_VERTICES (6*4)
#define NUM_CUBE_INDICES (6*2*3)

// Define the normals for the cube
D3DVECTOR n0( 0.0f, 0.0f,-1.0f ); // Front face
D3DVECTOR n1( 0.0f, 0.0f, 1.0f ); // Back face
D3DVECTOR n2( 0.0f, 1.0f, 0.0f ); // Bottom face
D3DVECTOR n3( 0.0f,-1.0f, 0.0f ); // Top face
D3DVECTOR n4( 1.0f, 0.0f, 0.0f ); // Left face
D3DVECTOR n5(-1.0f, 0.0f, 0.0f ); // Right face

// Front face
*pVertices++ = D3DVERTEX( D3DVECTOR(-1.0f, 1.0f,-1.0f), n0, 0.01f, 0.01f );
*pVertices++ = D3DVERTEX( D3DVECTOR( 1.0f, 1.0f,-1.0f), n0, 0.99f, 0.01f );

Отрисовка сцены:
m_pd3dDevice->DrawIndexedPrimitive( D3DPT_TRIANGLELIST, D3DFVF_VERTEX,
m_pCubeVertices, 4,
m_pCubeIndices, 6, 0 );
m_pd3dDevice->DrawIndexedPrimitive( D3DPT_TRIANGLELIST, D3DFVF_VERTEX,
m_pCubeVertices + 4, NUM_CUBE_VERTICES — 4,
m_pCubeIndices + 6, 6, 0 );
m_pd3dDevice->DrawIndexedPrimitive( D3DPT_TRIANGLELIST, D3DFVF_VERTEX,
m_pCubeVertices + 8, NUM_CUBE_VERTICES — 8,
m_pCubeIndices + 12, 6, 0 );
m_pd3dDevice->DrawIndexedPrimitive( D3DPT_TRIANGLELIST, D3DFVF_VERTEX,
m_pCubeVertices + 12, NUM_CUBE_VERTICES — 12,
m_pCubeIndices + 18, 6, 0 );
m_pd3dDevice->DrawIndexedPrimitive( D3DPT_TRIANGLELIST, D3DFVF_VERTEX,
m_pCubeVertices + 16, NUM_CUBE_VERTICES — 16,
m_pCubeIndices + 24, 6, 0 );

m_pCubeIndices + 30, 6, 0 );

Так вот, он зараза рисует три грани, вместо 6-ти..
Где я ошибся, подскажите пожалуйста.
