I have been following this tutorial : https://app.pluralsight.com/library/courses/disintegration-teleportation-reintegration-effects-houdini-2322/exercise-files, [app.pluralsight.com] everything works perfectly until the shading part.

In the video he uses clay as a material shader builder, then proceeds to editing the vop network. However, I can only find clay as a mantra surface in my Houdini version which makes editing the network a lot more complicated. This is probably a stupid question and I am very new to Houdini, but is there a way to use clay as a material shader builder(into a vopmaterial) ? If I just change the operator type, it's still not what I am looking for.
