I have built a water slide and pool and I want to make a animation of the water running down the slide and into the pool. The problem is I need the water to be created at the top and go away at the bottom to create a continues stream of water. What would be the best way to do this?

enter image description here


You will need an Inflow object and an Outflow object.

  1. Setup your domain object. Add a cube that encloses the entire area you want the water to go (don't make it to big though, as the larger it is the more CPU time your bake will require). Then add a fluid modifier in the Physics panel with the type set to Domain

  2. Add the inflow object at the top of the slide and the outflow object at the bottom. Add fluid modifiers with the appropriate types to the objects.

  3. Add an Obstacle type fluid modifier to the slide and anything else you want to collide with the fluid.

  4. Bake

  • $\begingroup$ The fluid obstacles aren't holding the water, do they need to be on the same layer? EDIT: Moving them to the same layer did not help. The water just keeps falling until it hits the domain $\endgroup$ – Qwertie Dec 16 '13 at 2:09
  • $\begingroup$ Here is the .Blend mega.co.nz/… Also the inflow object is not working $\endgroup$ – Qwertie Dec 16 '13 at 2:16
  • $\begingroup$ @qwertyk31 They need to have some thickness. Try adding and applying a solidify modifier. As for the inflow object, it's too small for the current resolution you are baking at. Either scale it up, or increase the resolution $\endgroup$ – gandalf3 Dec 16 '13 at 2:18
  • $\begingroup$ That still has no efect $\endgroup$ – Qwertie Dec 16 '13 at 2:23
  • $\begingroup$ @qwertyk31 Strange.. It's working for me. Did you apply the modifier? $\endgroup$ – gandalf3 Dec 16 '13 at 2:27
