Thanks for your reply. I’m still seeing the stretching at low velocities. I was seeing some jitter as well but that only occurs in cascade and the editor.
Here’s a video showing the issue I’m seeing. I set the particle size to constant x=25 y=100, I’m emitting particles from a sphere source in all directions. When I set the velocity to a low number < 1 the particles will scale on the y axis. In the video I turn on drag to exaggerate the what I’m seeing.
