Particle `Place on Ground` modifier and other similar effects

[Fortune117]

For?

S&Box

What can't you do?

In the legacy particle editor there were a bunch of useful particle position modifiers that were available. One of them was a 'place on ground' modifier. This would fire a trace down and move the particle to the hit position of the trace.

You could use it after a other particle positioning effects like place in sphere or place in box, etc, to get a nice shape of particles all along the ground.

How would you like it to work?

As a component that you can add like the other particle components. It'd hook in and modify the particle spawn positions after they're emitted.

What have you tried?

It's possible to implement this myself but it'd be more useful as a native feature.
