I´m tryng to implement env map (reflection) in the fixed pipeline like this:

   ZeroMemory(&stReflecMatrix, sizeof(D3DXMATRIX));
   stReflecMatrix._11 = 0.5f;
   stReflecMatrix._22 = -0.5f;
   stReflecMatrix._41 = 0.5f;
   stReflecMatrix._42 = 0.5f

   m_poD3DInterface->SetTransform(D3DTS_TEXTURE0, &stReflecMatrix);
   m_poD3DInterface->SetTextureStageState(0, D3DTSS_TEXCOORDINDEX, D3DTSS_TCI_CAMERASPACEREFLECTIONVECTOR);
   m_poD3DInterface->SetTextureStageState(0, D3DTSS_TEXTURETRANSFORMFLAGS, D3DTTFF_COUNT2);


It works, but just in a spherical object, because it isnt taking in to account the camera position, just the pos and normal of the vertex. Someone know how can it be done using the camera position?
