Foam at edge of sim

[cwalrus]

Hi guys, 

I'm making foam for my nice ship here:

 

But when I render it I get extra foam at the edges of the Flip tank, which you can see here at the bottom right:

 

 

and here in the viewport:

 

 

 

Obviously I only want foam where my "ship" - the static body - collides with the flip particles. I don't want them magically appearing at the edges of the tank. 

Any advice greatly appreciated!

Maybe this is too obvious, but can´t you group everything inside a bounding box around the ship (a big one) and erase all foam outside that group?

I've been doing that in a roundabout way - by creating an object to matte out the foam outside of the ship area...  But how would I do it your way? I've tried Blast, Delete, POP Kill... so far no luck.

 

Thanks!

You could do something like this. Alot easier ways to do this but, this is using nothing but sops.

Thanks -

for me the question is what to put where, with respect to a whitewater sim- so my best guess is to put a Delete Sop into the FlatTankFluid network somewhere... ? gonna try it....
