I have seen a "pump" volume/field used in pyro sims at DOP level to make the velocity field only affect density as it passes though this pump field area (defined with geometry like a Box). The setup uses the SOP Mask field in a Volume Source node to create the mask for this "pump" area. The settings are:
Source Volume: v
Target field: vel
SOP Mask: pump

Is there a way to implement this at the SOP level using the pump "mask"?

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?

Thanks everyone. I somehow manage to find the wrong syntax listed for the function on a search, it had things in the wrong order so it didn't make sense. Thanks for confirming this.
