Hard FX and parenting

[Zibi]

I'm trying to animate a sequence where the moveable rudder part of an airship is clipped by another object and smashes to pieces.
-I've been trying to use hard FX to do this, but because the rudder is parented to the airship it now stays at the start point of the sequence as the airship flys off.

Is there something I'm missing here? or does Hard FX just not work with objects parented to a moving object?

How do you have the collision options setup?

Ahh I think I should retract the query. I did a quick test in a simpler scene and it worked fine. I haven't really used Hard FX before in anger so I probably did something really stupid in my main scene.

But thanks anyway Larry
