VFX BezierCurve and RandomValue

Hi, 1. I have been unable to get the emitter particles to follow a
BezierCurve. Is my setup correct, or is there an issue with the VFX Editor?
2. Using RandomValue, is it possible to have each individually emitted
particle be assigned the RandomValue? From what I can tell, when using
RandomValue it is only applying a value once to all particles being emitted,
upon initial spawning…i.e. if I have a RandomValue for the a X velocity, I’d
like each particle to have a random X velocity during the duration of the
effect.

Hello @southoakco 1 - You have not provided any varying input for t in
your BezierCurve node. You have set t to a fixed value of 4, which means
your node will always return 0, according to your curve. You probably want to
plug a variable for t, that changes with time or position, etc… 2 - To have
a RandomValue node generate a different result for every particle, you want to
plug the particle ID as a seed for the RandomValue node:

That did it, thanks!
