Instantiating Particles on a Pre-defined Path

salimmatta

Hey guys, this galaxy is made by a simple plane and added material on it. However, I want to instantiate a particle system on but it has to follow the exact shape of the galaxy itself.

It's a mobile platformer game and I have to say i'm new to particle system in UE4.

Any help would be much appreciated )

You could set velocity over life and manually align it to the texture shape. You could also have a spiral shape mesh and spawn from its surface but the velocity wouldn't follow it.

I'm gonna try both actually to see which one is the best, again, thank you very helpful

Welcome. In the meanwhile I figured you could also use a vector field for this,which is probably the best way to do it,  but I'm not sure about how good that would run on mobile. You can find a tutorial video about how to set that up, on youtube.

The velocity over time solution that I mentioned, would look something like this:

Again man, I'm really thankful for your help ) big time.
