Hey Houdini Gurus,
I'm trying to do some of the intro fluids tutorials, and I cannot get the Emit Particle Fluid shelf button to create a default emitter based on just hitting Enter rather than some geo selection. I get this “No Objects Were selected” dialogue. What am I missing here?
H13.0.198.21

Try putting down a sphere first and then using the shelf tool.

It also would be best to update to the latest version of Houdini. That one is many versions old now

With each Houdini's major release, workflow changes.
In Houdini 13 you have to select an object first to emit particle fluid.
