Using an oject as a trigger for emmition

Hi guys/gals,

I want to be able to control a particle emission from the location of two intersecting objects.
So if one object is static and another moves through it, I would like the intersection points to be the trigger of the emitter.

Is this possible?
Any links to tutorials?

Thanks!

If it’s ok that particles will emit from the whole intersection area/volume you can try creating a third object which will be emitter:

-duplicate the static object and assign to it a boolean (intersect) modifier. The target of the boolean will be the moving object.
-create a particle system on the static object with boolean.
-in the particle setting enable “use modifier stack”. In the modifier panel the particlesystem have to be below the boolean mod.
-you will have to manually set start and end of particles emission when the objects will collide.

Thanks! Will give that a try
