I have a cube, and a particle mesh inside the cube which emmits boid particles. However the particles don't bounce off the inside wall of the cube but keep several cm distance to it. I would like them to fill the entire room of the cube while still bouncing off the wall.
I tried changing the "Outer and Inner" Settings but nothing changed.
How do i change the distance the particles keep to the wall? I would really appreciate any kind of help!
