Projectile particle effect trails that persist after collision?

I’m using Unity 3.4 still at this point, so none of the 3.5 particle features.

So for example lets say I have a projectile that leaves a trail particle effect behind it (for example, a Fireball that leaves a flame and smoke trail behind it).

Currently the only way I can get them working is they leave a trail, but as soon as the projectile collides with something, the entire trail disappears.

How could I change this so that the particle effect decays normally rather than instantly disappears when the projectile collides with something?

Thanks.

Anyone?

Would appreciate some help on this plz

Check your collision script. Maybe you are destroying the object there. If so, don’t destroy it, but make it kinematic and invisible for a given time, then destroy it.
Another possible solution is to instantiate the trail/particle. Instantiated object won’t depend on the projectile.
