if you program involve a skybox, you’d better render it first, since other object may need blending, if you render these objects before the skybox, you object will not show
the correct order like codes below:
1: g_SkyBox->Render(g_Camera) ;
2: g_Bullet->Render(g_Camera) ;
The incorrect order is:
1: g_Bullet->Render(g_Camera) ;
2: g_SkyBox->Render(g_Camera) ;
