Hello there,

I have a FLIP from which I want to generate foam. I used the whitewater tool from shelf and i've got my foam/bubbles/spray particles. The only thing is that those particles flicks, some of them just disappear then reappears randomly.

My main FLIP sim is simulated at 150fps and is working ok.

Any ideas ?

Many thanks.

Cheers,
Steve

Sorry, here is a better preview of the problem (foam particles in the movie) and a simple scene I reproduced showing the same issue.

Many thanks,

Steve

It seams like it has something to do with the combination of “Kill original particle” and “Emit from attribute” on the pop-replicate node.

Haven´t used the white water that much, maybe someone at SESI can clarify if this is a expected behaviour.

Thanks Mawi,

Tried without the pop-replicate node but I get the same issue.
