Case in point, I would like to use the circle emission shape to spawn a burst of uniformly spaced particles around the center, shooting off at the exact time.
Like the same angle between every and all particles, but I haven’t been able to do that, I tried to tweak everything I could but it looks hardwired for random emission.
I did it by setting the emission rate to ‘bursts’ under emission rate and then also changing the ‘Arc’ ‘mode’ to ‘burst spread’ which you can find under ‘shape’.
I know that this is 2 years old now but if anyone else stumbles across the post as I did 5 min ago, maybe it can help you/them.
