Problem with halo.Add and stencils

[AtomicTACO]

Hello,

I created a heads up display for someone, and here is a picture of it:

I used stencils to achieve this effect. However, the downside to the heads up display is that when I pick up a prop with the physics gun, the menu turns into the following picture:

It seems the physics gun uses the halo.Add effect to accomplish the outline around props. I don't know why it breaks my heads up display. Can someone please help me out? Here is my sample code:

    render.ClearStencil( );
    render.SetStencilEnable( true );
    
    render.SetStencilCompareFunction( STENCIL_ALWAYS );
    render.SetStencilFailOperation( STENCIL_ZERO );
    render.SetStencilPassOperation( STENCIL_ZERO );
    render.SetStencilZFailOperation( STENCIL_ZERO );
    
    surface.SetDrawColor( Color( 0, 0, 0, 255 ) );
    surface.SetMaterial( white );
    surface.DrawPoly( p1 );
    
    render.SetStencilCompareFunction( STENCIL_EQUAL );
    render.SetStencilPassOperation( STENCIL_INCR );
    render.SetStencilReferenceValue( 1 );
    
    surface.SetDrawColor( Color( 255, 255, 255, 255 ) );
    surface.SetMaterial( car_diag );
    surface.DrawTexturedRect( 0, ScrH( ) - bh, 1024, 1024 );
    
    render.SetStencilEnable( false );
