suddenly there are some strange lines. - cgdvs - 03-01-2022
HI，Tyson!
I'm not sure if this is a "bug".
When a particle draws a solitary line, suddenly there are some strange lines.

Yea, that's pretty strange! What's happening is that the Spawn operator is integrating the particle velocities in order to calculate the travel distance...but then the Actor integration is returning particles to their actor-relative positions. If you add a Display Data operator to the Spawn event and turn on velocity vectors, you can see this.
A simple fix is to just add a Stop operator (with timing = continuous) above the Spawn operator, to kill those velocities.
The real question is why those particles have those large velocities at all...I will look further into that.

Update: the velocities being so large on the first frame of a rig particle's life is a bug that will be fixed in v1.00003
