mix shader depending on distance from surface

Recommended Posts

I'm trying to create a ice shader in houdini base on this tutorial:https://www.youtube.com/watch?v=MeObbrfCSUY

Around 5:29, he is talking about using ray length to control the mix alpha for transparency shader and sss shader, so that sss only appears on top of transparency material. How do you do that in Houdini( to layer ss material on top of transparent material)?

Any helps pls? I have a test hip file attached below.
