Description

Observed: When any thin-skinned vehicle (from civilian sedans to armored humvees) is destroyed (by any weapon or cause), a large, artillery-sized explosion results. This is probably the cookoff system burning up the fuel in the vehicle.

Expected: Large fuel explosions in thin-skinned vehicles should be rare. Even then, they should appear similar to the BI-default secondary explosions. They should not occur immediately after vehicle destruction 100% of the time. If they cannot be implemented realistically, they should be removed, as currently ACE automobile destruction is even more Hollywood than vanilla.

Repro: Use a trigger to setdammage 1 on a civilian lada, or shoot it in the engine block with a few hundred SAW rounds. You should see a big fireball, like a tank exploding.

Most likely, thin-skinned vehicles need their own cookoff script. I'm not saying that gasoline in a burning car should never explode, or that ammo cookoffs are impossible, just that currently a 1% chance event is happening 100% of the time, always at the same time interval. Further more, I am skeptical that every time a humvee burns, the ammo loudly cooks off. The majority of the vehicle is non flammable and the ammo is not encased in an NBC-protected armor shell that will trap heat and reach extreme temperatures. In my opinion, open-topped and thin-skinned vehicles should have low probabilities of ammo and fuel cookoff. The very presence of flames in every wreck is a damage model limitation that I am sure ACE devs would remove if they could.

Possibly the solution would be to exclude unarmed vehicles from this effect, and include for all the rest some type of variable like percentage of chance cookoff will activate.

This way from what I've seen in MP every single vehicle - being it MBT, IFV or anything - has this effect. Not sure why was that happening in such amount but I suspect it has something to do with third party addons used by clients such as Blastcore Visuals and JTD FireAndSmoke.

Realistically fuel tanks can hold burning fuel as a safety mesure (why do you think cars don't explode at fuel stations when static set the fuel off?) the only thing that should really be cooking off beyond vanilla is the ammunition.

When a Humvee burns, the ammo inside cooks off most of the time, actually. Especially if its an IED strike...

The ammo may not be in an NBC shell, but it most definitely isn't inside any kind of protected container. Also, the Humvee may not be very flammable, but all the gear the soldiers/Marines have most definitely is, and man, does it burn.

Is this somehow hardcoded? no matter what I disable in the scripts, there is still a huge blast as initial eplosion and smaller ones occuring after that from time to time.
