 So you want to parent one particle to another not a problem. Let's say you have a fireball and you want the embers to follow that ball when it's moving around. Normally you will see something like this, which is obviously not what you want to fix it on the child particle, remove the spawn module and replace it with a spawn particle from emitter. Then type the name of the particle you want it to parent from and say fix issues underneath a sample particle module will be automatically added click it and under position sampling say apply to attribute you're done now you can see the sparks follow the ball the way they're supposed to quick tip if you have other position modifying modules like a shape location sphere make sure those happen after the sample module otherwise you're going to get really weird things like this anyway hope that helps and as always hope you have a fantastic day and I'll see you around
