Airplane (208B) crashes without touching anything (near trees)

ISSUE DESCRIPTION

Description of the issue:
I was taxing with a 208B between two tree, with at least 1m from the wings on each side of the aircraft. The airplane crashed screen come up, without actually hitting anything. I was able to maneuver between buildings and aircraft with this precision, but around trees it seems like there is an invisible hitbox. This happened to me once before already when I was spawning between two tree in a mission, I tried to get out of there and haven’t actually touched them, still got a crash screen. At the time I thought it’s just a buggy airport, but I think the trees or some trees have hitboxes that are invisible. It is also ridiculous as I was going with a speed that was barely rolling, so there was no inertia in the hit, but that aside, there was nothing to hit.

[PC Only] Did you remove all your community mods/add-ons? If yes, are you still experiencing the issue?
I never had addons or mods

FREQUENCY OF ISSUE

How often does this occur for you (Example: Just once, every time on sim load, intermittently)?
Two times sofar, but sorry I won’t wreck my aircraft to test it

REPRODUCTION STEPS

Please list clear steps you took in order to help our test team reproduce the same issue:

Note: Currently only confirmed for 208B

  1. Manouver close around a tree (maybe specific tree types, I’ dont know, if that helps, it was in Central Africa and Madagascar) with around 1m visible distance between the wing and the tree
  2. Get airplane crashed screen
  3. Alt+F4

YOUR SETTINGS

If the issue still occurs with no mods and add-ons, please continue to report your issue. If not, please move this post to the User Support Hub.

What peripherals are you using, if relevant:
Not relevant

[PC Only] Are you using Developer Mode or have you made any changes to it?
No

MEDIA

Please add a screenshot or video of the issue occurring.
Cant share a screenshot because you put an aiplane crashed screen instantly, so there is not even a chance to catch it.

I was in a large group flight last night, many people had weird crashes with trees also, almost like they got sucked into them (much to our amusement), so yes there’s definitely something amiss

Possible fixes for the developers:

  • Build higher fidelity tree hitboxes that are enveloping the trees as they are shown, this might be more performance hungry though
  • Build tree hitboxes only around the trunk, as this might happen because of the branches 10 feet higher somehow have a hitbox at the bottom of the tree as well, this would probably be the easiest
  • Maybe quick fix is to remove trees from parking stands, taxiways or anywhere near where an airplane could go in an airport at the very least

Further suggestions:

  • Some trees seems like they are starting underground, so some trees have a wrong placement on the terrain, i guess there are several post of broken tree generation, so this might be related, however the hitbox should still be more sophisticated than it is right now

Might help to know the type of aircraft, too, in case there’s trouble with a hitbox on that end.

Thanks for the hint, i will update the post. Its a 208B cargo. It might be relevant, however I had no problem yet to maneuver other obstacles (close to buildings or other aircraft).

Absolutely! You never know when it might make a difference - we might find that all 208s are bugged. Cheers! :slightly_smiling_face:

I had this happen in the 208B during the turboprop check ride in career mode, but it was with a building.

During taxi back to parking at the end, it suddenly jerked right as if it had a wing strike with the hanger behind the parking spot, which resulted in a crash failure. The wing tip was was about 5-10 ft. from the building when it happened. The next time I tried the flight, I stayed further from the building and didn’t strike it.

I voted, but do think it needs more investigation to see if it’s the 208B specifically or scenery errors.

I changed the title to include 208B. So far then it is only confirmed for that, however the 208B is probably one of the most played aircraft at the moment, so I still want to keep open that other aircraft might experience something like that.

As I mentioned, I myself have never had problem with buildings or other obstacle till now, but it can indeed be a scenery problem, maybe hitboxes loaded offset from the visible scenery and it can effect any type of scenery at any point. It can also be the 208B that has an offset hitbox sometimes.

The hitboxes on certain objects/aircraft can quite generous. You can check this using the SDK like I did here Taxiing from/to runway at Rijeka [LDRI] causes "collision with an object" - #8 by Speed1994

Well I understand it might be because a crude hitbox is less performance hungry, and its by design but then:

  • It is not consistent. I was able to maneuver closer to objects and still crashed further from a tree.
  • The missions spawn me next to trees, leads me through places where I barely fit or not at all and penalizing highly for crashes.

I think a more lenient hitbox (like trees only have hitboxes at the trunk for example, but if its the aircraft then that) would be better than a larger hitbox. Since till now I only experienced this with trees and only twice, it seems like it’s not happening always, so I would still consider this a bug as of now. If it turns out this is by design, then there has to be a better way.

Just for the humor, this was the mission I got after the invisible tree crash. Some trees there clearly start underground, they are tree canopies that are visible. And no, I didn’t attempt this mission :smiley:

Ironically enough, my case happened the very first time I flew the 208B, and only 3 times in total. I usually fly the other missions with a 172. I haven’t really flown others or used free flight because the only two planes I actually want to fly are broken beyond usability in FS24 (The CJ4 and DA40 NG).

I can’t think of other times where I got close enough to other objects to risk a collision.

Seems like the issue zooms to the 208B so far. Honestly I don’t think I was going much near trees or scenery with other aircraft. The 172 I had very close maneuvers to aircraft but not trees or buildings as far as I remember. With my 208B however, I visited a lot of small, remote airports, well mostly those actually, so I was maneuvering a lot between objects. The two time I crashed was with trees, but seems like the 208B could have the problem.
