Hi, was just trying to play around and learn about refraction by playing with your sample refraction shader in the examples.
When I break the node connection to refraction output, and then attempt to-reconnect it, it refuses to connect. Even without modifying the existing node network. I try reconnecting the Multiply back to Refraction and it just doesn't work.
Not sure if this happens all the time with the refraction output, but thought you would like to know.
