Zmodeler: Door Collisions

I'm not 100% if this is the right place to post this topic to get the right info I need but I'll give it a go. I've been googling and searching some other forums for a while but haven't found a solution that I understand exactly.

I've been editing some of the default GTA IV cars to turn them into police variants (Rebla, Vincent, Vapid Cruiser for example). Unfourtunately though I've had a common problem with all the vehicles I export from Zmodeler. When I get into game the car doors (and I think the boot and bonnet) don't function properly. What I mean by this is that when I open the doors (and leave them ajar) they don't have a collision and I can just walk right through them. If I shoot inside the car where the door was the bullets hit an invisible wall on the outside of the car rather than passing through inside it. I'm not exactly sure but I think I'm having similar troubles with the boot and the bonnet in that the boot doesn't open and close smoothly, it'll just switch positions from all the way down to all the way up rather than actually moving smoothly.

I'm pretty sure it's related to collisions or rotational limits but I haven't yet managed to find out exactly how to fix the issue.

Any help from you experienced vehicle modelers could provide would be much appreciated.

Edit: I think I have figured it out following what is said here: http://forum.zmodeler2.com/viewtopic.php?t=5577 I had to edit the properties of my rotational objects (doors, boot, bonnet) to rotate as spheres and then set the RotY and RotX values for their rotational limits.
