    Hi there!
    As first I'm using Unity 2018.2 HDRP

    I'm trying to make a water sprinkler, as start I only animate the start speed and I would expect a continuous line, but I'm getting this stutter effect, it seem that particles are grouping leaving a space between each group as you can see in the image and video below:






    Thx ^_^

    I think the start speed isn't factoring in the sub-frame interval. So all particles spawned on a frame get the same start speed. Then on the next frame, all the new particles get the next start speed value along the curve.

    You may submit a bug report via the Bug Reporter in the Editor and we can look at fixing it.

    Thanks!
