Refraction not showing any colour - Maya

Following along to Lee Griggs tutorial and almost there, but for some reason the refraction is grey. Do you have any advice for fixing this?

It looks like you are missing this step from the tutorial (see shader at bottom of tutorial):

  • Connect the same projected texture to the Specular IOR and Transmission Color via a Rangeshader. The Range shader is used to define how much the texture will refract and can be used to fine-tune the effect.

Are you using a Al Shader? What version are of Arnold are you using? Al Shader might not be compatible.
