torus volume axis field doesn’t guide the motion of the particles
as expected because the initial emission velocity of the particles
dominates the motion of the particles rather than the field. You
can use a particle object’s Conserve attribute
to scale down the emission velocity’s influence and increase the
To adjust the velocity of moving particles
- Select the particle object and set the Conserve attribute
to 0.8 in the Channel Box.
By changing the Conserve value
from the default value, 1, to 0.8, the emission velocity’s influence
on the particle motion decreases and the field’s influence increases.
- Go to the start of the playback range
and play the animation. Notice how the particle movement now conforms
to the shape of the torus volume field.
