Bounding Box to contain Particles emitted by ParticleHelper?

Questions
1

Hello,

I’ve got a living room environment with a sliding glass door through which we want to see rain particles.

The problem is that the default rain particles, created by ParticleHelper, seem to encompass the entire camera view / scene’s bounding box.

Is there any way to use the ParticleHelper in a way that will constrain all particles to a BoxEmitter, without creating our own particles and using the ParticleSystem API? And if not, is there any tutorial on how to keep particles within a bounding box using the ParticleSystem API?

Thank you.

Jeremy

Unfortunately it does not work this way, you have to setup the system (even afterwards by using the particle editor: Introducing the Particle Editor Part 1 - YouTube

You need to configure the emit force and the lifetime to make sure they remain inside your box
