LiquidSrc Question or possibly problem

Hey Everyone,Short time lurker, first time poster.

What I’m trying to do is simulate a jet of water emitting from underwater (up through the surface)basically a large fountain type effect caused by an underwater explosion viewed from above the water. So after the momentum of the initial discharge has faded the water should fall back down and splash in the pool. What ive done is animated a liquid source to do the initial discharge from a surface force object with a specific Polygon ID. The discharge works great,but no mater what I seem to change the water never comes back down to earth. It just seems to hang in midair. Am i missing something very obvious or is this a bug?

File attached if anyone has any thoughts.

Hey,

If it’s Liquid or Splash particles, then you have to check the gravity or the scene scale parameters (respectively under the Dynamics and the Grid rollouts) - if the gravity is too low or the scene scale is too high, it will take a loooong time for the particles to fall back down. If these are foam particles, then there is a dedicated option for that - falling speed under the Foam rollout. You can determine which particles we are talking about from the Preview rollout’s particle preview settings.

Hope this helps :slight_smile:
