Ocean in a nutshell, unable to kill particles around completely

[olika]

Running into a problem here,
mabe someone can help.
I'm trying to sim an ocean in a geometry. Also in a pretty small scale (Cylinder is about cm 30 in size)
All fine, but i'm not able to kill all particles around the cylinder with the particle tuner.
Do i miss something? see screenshot and scene attached.

You can get the scene here:

Thx in advance!

Hmmm, haven't looked at the scene yet, just noticed that the distances are pretty narrow - 1.0 and 0.1 are in voxels, so maybe the chances that particles enter this range at the moment the tuner works is very low, and so the particles skip it?

hi Svetlin and thanks for fast reply!
*Update: Seems Having a tube around and make it solid and clean inside seems to does the trick

Na sheiz! Doesn'T work out with the clear inside cause then the waves crashing at the border damn

Ohhh, I see what's going on with the Tuner - you are using a render cutter for the mesh, but in fact there is real ocean simulated inside the entire Simulator.

So the waves keep creating foam and splash - they show up for one frame and then die immediately by the Tuner.

So there are two things I would suggest:
- Render time solution - add a cutter to the particle shader as well, and these particles will not be visible
- Simulation time solution - add the Cylinder as a birth volume to the splash and foam so they would not get born outside it.

Hope this helps

Hi Svetlin,

thx for investigating! really appreciated.
Yeah cam up with the birth volume silution aswell and it's workin!
Can't wait to show results
