Is it possible to remove "clear out" an area of particles?

Hello people, so I was wondering if it was possible to use an invisible part or another method to clear out a portion of particle. So for example lets say I wanna fill an entire map with a thick layer of particles, but make it so the particles are absent within a X stud radius or perhaps have it so when you shine a flash light, the area illuminated makes the particles go away in a sense. On another note, can particles have collisions?

Thanks for taking the time to read my questions. There'll probably be more to come so be ready world.

To what I know and understand, the only part that would really have the ability to "clear out" parts of a particle is a part with the material of Glass. Now of course it would look weird. So you have a couple of options.

1. Try attempting to implement glass into your game somehow. This will require some thought

1. Make more particles. 1 Particle Emitter is not always enough to make what you want.

1. Try using a different shaped texture. The texture of the particle is important, you can manipulate the texture and it may create what you want.

1. Mess with sizing. Did you know that you can change the property of sizing so that it actually kinda "Tweens" to different sizes at different times?

1. Mess with properties in general. There are so many properties that can help solve your issue. I suggest check out these: LifeTime, Rate, Texture, Size and so on.

Hopefully this may have "Helped" you. There isn't really a way to do what you want. The most simplest solution is to make more particles.

Best of luck developer!
