Hello, Right now I'm working on effects using version 2017.3.1p4's timeline. And I'm having problem with the control track playable asset clip's random seed. Before when I used version 2017.1.2f1, this random seed didn't seem to actually do anything, but right now it's affecting all the particle system's random seeds and forcing them to be the same value. This is really troublesome when I want to use different seeds on different emitters or when I want to use auto random seed. Is the control track's random seed actually needed? Like because if we want to use random seed we can just set them ourselves on each emitter. If it's possible then can I ask for a way to remove this?
