I was following the Destruction FX tutorials from Houdini and in lesson 7 the Material Library in Solaris is used to bring in the shaders from the SOP level by clicking on the Auto-fill Materials (once you import the USD file of an RBD simulation).

However it is not showing a popup window when I click on it in Houdini v20.5 (Mac OSX). What could I be doing wrong, or is there a bug in my version of Houdini?

Can anyone confirm it works for them in this version?
