2 Play back your simulation.
Notice that the nParticles no longer pile up, but blend and overlap with
each other.
Each nParticle has an outer boundary that determines the distance
between the nParticle and an object at collision. The Collide Width Scale
attribute sets the collision distance between the nParticles and other
Nucleus objects. The Self Collide Width Scale attribute sets the collision
distance between self-colliding nParticles.
By default, Collide Width Scale and Self Collide Width Scale are set to 1
for normal collisions. Turning off Self Collide is like setting the Self Collide
Width Scale to 0.
3 Turn on Self Collide, and set Self Collide Width Scale to 1.5.
4 Play back the simulation.
Notice that the nParticles appear to collide with each other when they
fill the bowl, but they don't touch one another. The gaps between the
nParticles are due to the increased Self Collide Width Scale.
