Just noticed this.. It's as if the tracks aren't there!

Should be a lot more like this: https://www.youtube.com/watch?v=MLz9UR_k-ms

This is because there is no real track simulation. The tank has more wheels then the regular car. That is why it is bump every time when the obstacle is under the next wheel.

Yes, that is the whole point of this ticket. The wheels are the only things simulated but turning is handled by a force being applied to the whole tank (according to another forum user), not even the wheels contribute towards it.

Well, in my opionion, the whole movement of tanks needs an overhaul, and proper trank simulation is only one part of it. UPVOTED.

Definitely agreed. In my opinion physics of all vehicles should be overhauled. Both wheeled and tracked.

I had created a video describing the shortcomings of a significant portion of the vehicle physics.

Thanks Dunk for that awesome video.

Here's some reference, how a tank suspension should behave.

That was the video that inspired me to make my own. ^_^

Out of all that the most annoying thing is that tanks lose their momentum as soon as the tracks leave the ground even if only for a fraction of a second. Cruising along in a MBT at 60 km/h, then suddenly a small drop in the ground and the tank gets superglued to it. Come on!

Sadly many of these issues are probably impossible to fix with the current engine.

Tank tracks dont exist, they are just visual. Nvidia PhysX model is based on wheels, therefore it will behave like wheels. PhysX doesnt allow complete and very realistic track simulation.
I don't know of any other game that has real tracksimulation, and i doubt we will see one soon because realworld Trackphysics are complex and calculationintensive.

Real track physics are very likely out of scope for Arma /it's unrealistic to expect it. As long as 0-speed torque is fixed (/ the clutch system is fixed) and controlls are repaired it will be much better.

@pops I could be wrong but I think it is because the mesh between the road wheels and front wheel contacts the ground and grinds it to a halt.

@Fennek Yes, I have explicitly acknowledged that I was aware of that fact that they are visual props in the comments and passively implied it in the ticket.

So in the end this is a problem with PHYSX? How do you think they could work around it, use two dozen little, simulated wheels for each set of tracks and the gap between the drive and road wheels? Even if they fixed the clutch it is still bouncy as balls when something slides between the wheels, jarring as well making it liable to be able to get stuck.

physx simulation only allows 20wheels at max. Tank wheel count is already high (Kuma= 18 wheels). There is no workaround possible with extra wheels.

Darn, what about making the virtual wheels big enough that they overlap and add one more between the road wheels and front drive wheel? Can the engine handle that?

Voted. this is one of the biggest concerns for me with Arma3 at the moment.

Odd, you link my video seany and my Feedback ticket loses a negative vote but my video gains one. Tut, tut, tut, who could be responsible? :3

In all seriousness I really hope to eventually see a complete ground vehicle overhaul because they way all of them handle just feels so damn off putting.

P.S. As for armored vehicles burying their noses in the dirt:

Tank don't care, tank don't give a shit.

I highlighted this vid over on the Bis forums yesterday, so you Probably got a vote down by some bis forum troll who doesn't like me/you/or is having a bad day..I dunno. I up voted both here and your vid.. Good work btw, I hope we can get it fixed!
