I'm working on a quite heavy scene and I've noticed when I select a node with display or template flags off houdini still cooks it to show a “thumbnail” of the node in the viewport.
On heavy scenes it's quite annoying

Cheers !

If you RMB click on the Select Geometry tool (2nd icon down on the left toolbar), you'll get a menu with a radio list at the bottom - “Show Display Operator” and “Show Current Operator”. Change this to show the display operator, and it won't display the current geometry in the viewport when you select a SOP.

Just re-installed Houdini recently, I thought the cooking was broken :o
Can "Show Display Operator" be the default?
Selecting a node to move it or edit parameters doesn't mean you want to cook it.
or maybe it's just me?
And you have to restart Houdini for that cooking behaviour to change. not super intuitive.
