your welcome.

Hey,

Narrowed it down to the Simulate Air Effects option. Could you try disabling it as a workaround until I figure it out?

Cheers!

hi there,

yes that's what i found out also. i tried several values included simulating with or without simulate air effects a few weeks ago. is this because the foam particles would like to behave like mist? it seems like this. i will try it again without simulate air effects. i also went back to the original scene, the one i sended you in the beginning with my favourite settings. i got also the foam issues. i then created a new riverbed, a new mesh and it got better. know i also try it without simulating air effects on. thank you. Cheers

Hey,

The fix will be in tomorrow's nightlies - the thing was that when there were air pockets between the liquid and geometry, they were treated as if they were free air and the velocities were not scaled right, so they became huge and cause underwater explosions. The foam getting shot in the air was actually just a consequence of that. Please ping me if there are still issues even without air effects or after you try the nightly

Thanks very much for finding this!

Hei,

So i simulated a highend Simulation with, and one without "Simulating Air Effects". Each one of them is labeled accordingly. It seems that the one "without" is indeed more stable, but there are some Trails of Foam shooting in the Air. The one with "Simulating Air Effects" is unstable and got the exploding Foam
I used the same Nightly Build as before. Soon i try the new one. I am interessted in helping you find Issues or Bugs. Also i like it to try out New Features. thank You. Cheers.
