How to customize shape of particle spawn location?

[hib0823]

I am trying to make vapor clouds on aircrafts like this.

This is my best what I can make now. I set the particle spawn location as Box/Plane and rotated somehow.

The amount or appearance of particles is currently not an issue. I need the particles to be spawned and ended like this.

So this might need different particle lifetimes for each spawn point on the red line in order to end all together near the green line.

I tried setting the particle spawn location as a flat cone trying to look like a triangle. But unfortunately no matter how I put a big number in the cone angle, the cone wouldn’t wide up.

How can I customize the location of particle spawned?

One of the modules in the particle update section is, ‘mesh location’. You can use a mesh to set this.
