– As ‘Path’ only works for Keyed Particles, for this video I had to create two Particle Systems.
– The red vertical lines are the particles of the 1st Particle System and rendered as paths.
– End = 0.5 : the red lines cover the half path to the second Particle System (0.5 = 50%).
– End = 1 : the red lines cover the full path to the second Particle System (1 = 100%).
