what causes a crash?

Hey guys,

I'm making this boat at the moment. Switching between VC and the exterior results in a crash. What can cause this? It must be something in the aircraft.cfg

Hmm I have not made a VC for a ship.... try one of the other cfg 's out there for other ships with VC... don't change it... just drop it in... all the effects will be off of course... but see if it comes up fine. If so then you know it is that for sure... and can then examine the file to see what is missing.
 
Cees,

I assume then that you have an exterior model, and an interior model ... 2 models.

1. Are the models the same size, located at exactly the same coordinates? Verify.

2. If so, then you may have a scaling issue with one of them (if you are developing in gmax).

Select each of your high order nodes (exterior, interior) and reset the scale for the pivots on them.
This ensures they will be exported at the same dimensions.

If you simply clone the exterior for the interior model, then simply reset the scale for teh exterior model before cloning.

3. Do you have crash points setup in the contact points section (type 2 points), if so, comment them out and try again.
If this is the cause, you may want to reestablish them by getting coordinates from your design program.
 
Along the same lines as Milton's #3, make sure that any contact points have a FPM damage tolerance that's high enough to withstand a bump.
 
Hi Milton, Tom,

I deleted the VC as the boat is meant for AI. Now everything is fine.

Tom,


What is a 'FPM damage tolerance'? And where do I change that?

Cees,

that'll probably be 'feet per minute' as an impact speed on a contact point. Tom's point is that sometimes changing views can make a plane with poorly set contacts 'bounce' when switched and if it also has to low an impact speed, plane crashes.

Jamie's right. I'm talking about the fifth parameter in every contact point line, the "Impact Damage Threshold." If the number is set too low, just the slightest bump can trigger damage or a crash.
