Hi everyone! I'm brand new to Houdini and trying to learn the ropes with the Rebelway Fundamentals course. It's been fantastic so far, but I'm stuck on a viewport issue. In the Vellum section, the instructor adds a rubber toy object to the scene. Oddly, it's visible in the viewport even though there are no display flags (neither pink nor blue) enabled on the node. He's only selecting it in the network editor. I'm completely stumped. Any help would be greatly appreciated!

Hello flobs, by default, the selected (current) operator's geometry will be displayed. That behavior can (and should, IMO) be changed by right-clicking on the second Geometry Select Mode button at the top of the left sidebar of your 3D view and switching from Show Current Operator to Show Display Operator.
