Following this very helpful youtube tutorial Blender Physics - Creating a Splash with Mantaflow

But then I need to find out how to time this object: (type: flow, flow type: liquid, flow behavior: Geometry) to emit fluid at a certain later keyframe, and not at frame 1.

How do you time the emission?

    $\begingroup$ Animate some properties of the flow emitter, I’d expect. $\endgroup$

  • $\begingroup$ You can keyframe the "use inflow" checkbox on the flow object. $\endgroup$ Commented Mar 31, 2022 at 17:24
  • $\begingroup$ I tried "use inflow" and limited to one frame, and even still, it gushes out 3 or 4 mesh size particles. How can I limit it to just one mesh worth of particles? $\endgroup$

It's the Offset under Cache in the domain object. But still not sure how to make each individual flow object have its own offset amount.
