reflect on backside

[matthew999]

Hello All,

I was wondering if someone could tell me if im missing a trick here. I am trying to render soapy bubbles and want double reflections so the hdri reflects on the backside.

see attached photographic referance, the sky is reflecting on the inside surface aswell.

I tick the reflect on backside tickbox and nothing happens?

am i missing something

cheers
