I noticed that when using collisions on the particle system the collider is only spherical, while I need a box shaped one; considering that most of the the particles are quads, this makes sense.
Is there a way to change the shape of the collider? I see there is a scale factor, it would be useful to scale it on one axis but that’s not an available option too.
Well, can’t you just add as a component a “cube collider” like any other objects ? I’ve never added a collider to a particle system but it would be logic.
