Fill a Cube with Smoke Particle System

Questions & Answers
1

Hello,
I’m using the standard Particle System package provided by Unity (5) and I’m trying to fill a hollow cube with smoke.
My cube is made with 6 planes facing the center of the cube. Each of them has a mesh collider.
The particle system is a default smoke particle system emitting in all directions from the center of the cube and I enabled collision with World Mode.

However it seems that the particle system does collide with the cube but in some way extends slightly beyond the edges of my cube.

Any idea how I can fix this? I’m new to this system and it would be much appreciated.

Thanks!

You could increase the radius of the particle system’s collider so that it collides earlier and the smoke remains inside. Or make the mesh into box colliders.
