Direction of mirror reflection

Hello,

I made a simple reflective material in blend4web but the direction of reflection seems strange. ( I attached the image) I want to have the reflection of bottom part inside the mirror, what can I do to have that effect?

Thank you

You should use an Empty with correct rotation for mirror plane
