@KaiKostack Well then good job on finding it! Fluid particles are something I love to work with and I would hate it if they were like this :D
-
i could hear the shore (:
-
I will just know how to make the particles solid coz my particles is a bit halo or something like that i just whant them to be spheres instead of halo balls :D hope you can help me!

@MultiFantasyboy same here bro

You need to increase the ammount of subframes. Blender cannot calculate accurate particle physics if there are too many particles with not enough subframes

@IndefiniteDementia It wasn't possible by the time I made this video. It was a bug in the collision code, which have been confirmed and fixed shortly after I made it public. Back then fluid particles were completely unstable when a collision object was included.

How did you make the particles spawn all at the same time in 3d space? When I do it, they only spawn at the surface of my mesh over a period of time, I cant make them spawn all together or else it explodes - literally

@blazraidr You can switch the particle system emit options from faces to volume. The rest you can see in the video, just don't make it to dense or reduce the particles influence range.

Is the chaos demonstrated above like boiling water? I wonder if it is not a deviation from the way real water works, because real physics does not have sanity checks on velocities.

@nhnifong Real physics doesn't have bugs either. This was just to prove there was a bug in the collision code which produced NaNs leading to this kind of behavior. It has been fixed now.
