Hi Guys!

So i'm trying to do this simple flip sim where i have an emitter inside a teacup and i just want to fill up the cup. It's is definitely water tight, the only particles leaving the cup are over the top, but as you can see from my flipbook below the particles just start multiplying on their own when they land in the saucer, which is causing them to go everywhere. It is worth mentioning as well that the particles are only set to emit between frames 0 - 24 so i'm not sure why they're multiplying.

Any suggestions as to how to stop this would be really appreciated!

Maybe you check what your particles do on collision?

If that does not help, try adding contraceptives

At closeer look, the particles reaching the saucer are “dancing” around.

Try placing a delete sphere with delete non-selected around the cup.

If even that does not help, I am clueless.

(The environment for your particles is good then, they go forth and multiply…. SCNR)

An other hint would be to use a _thicker_ proxy geometry for the simulation. decreasing the time step would also be a hint. (Or increasing substeps)
