micro88 posted a topic in EffectsHello, I have set up a simple narrow band flip tank and am dropping a small object (cosmetics bottle) into the tank. The issue im having is on the first frame that the object collides with the fluid it shoots a bunch of random particles out that escape from the narrow band and then re-collide with the underside of the fluid and cause ripples on the surface that I dont want to create. The RDB sim is running at a time scale of 0.05 and gravity is the only force in the scene so its moving very slowly. The time scale for the flip solver is 0.1 to get some splash, but as you can see from the attached photos its not anything crazy. Can anyone suggest a way to either stop this from happening or kill these particles before they collide with the narrow band? Im not the most versed at flip so this may be a very quick fix Appreciate any thoughts or help with this!
sipi posted a topic in EffectsHello, I have noticed something interesting which I don't understand, but maybe somebody out there does. I created a Wave Tank shelf tool then a sphere and I hit the Deforming Object shelf on the sphere. Now I'm checking the OUT_INITIAL_VELOCITY node with PointsFromVolume and volumeTrail nodes. When I wire the collision geo into the collision input of the OceanSource node the velocity is become wierd as you can see, and it affects on the simulation in a bad way. It's just shelf tool! I didn't make any changes. I use 17.0. Is it normal or is it a bug or what is it? Is there anybody, who knows it?
