Hi guys, I'm new to Houdini and I am following the CREATE A TASK WORKFLOW TO BUILD CITIES [www.sidefx.com] tutorial, but I am stuck on the part it asks me to create a Geometry import node:

Add a Geometry Import TOP. Name it building_merge. Set Work Item Generation to Dynamic and turn ON the Merge Input Geometry option

And I can't find the Merge Input Geometry option anymore. Where has it gone? Thanks!
