A question about Physics Control!

I’m trying to use PhysicsControlDriver from ContentExample on a Chaos Vehicle and it’s behaving strangely, kind of jittery/lagy.



What can i do?

Disable collision?

Between Vehicle and PhysicsControlDriver?

Not sure, not 100% certain what’s really causing it but I’d start with ruling out any collision shenanigans. The driver’s skeletal mesh itself perhaps?

I tried putting the PhysicsControlDriver over the vehicle so it wouldn’t collide but the same result.


And from the PhysicsControlDriver I set all components to ignore the Vehicle. Same result

Are you on 5.3 / 5.4 or lower? This stuff is experimental - I found 5.4 more buggy than 5.3, for example.

5.3

Out of sheer curiosity, does this flicker only manifest while you move? What if you just steer in place?

nice project i like the way u think
..im trying to make sense of it but i failed to re-create even hands constraint not to mention gear shifting ant for cinematic purposes only
so i copy replace the guy had a lot of fun with adjusting my guys hands but somehow i menage it
i can imagine the pain of putting this in a game
i mean this looks very very usful for a million tousands applications in a game so one dares to try
not to mention entering a vehicle like gta.. i have it planed put all those scene ■■■■■ like the wheel has and gear does and switch hands like gears while entering stolen vehicle and handling doors with some logic left right hand depends on location rotation but i value my sanity also so i quit
i’ve done all like the ritual suposes one does
waited till the stars align
took one of my comodore cassete and buried it under the north side of tallest oak in forest
i’ve watched all prismatica and ask a dev tutorials
even the allmighty claude try to help but my brain said no no no

Hi there.

This seems to me like one frame off error.

If the child actor is the driver and it is the only thing jittering it might be because of the tick order. Sometimes driver ticks before the forklift.

Can you try moving the driver’s tick post physics and say if it has any meaningful difference?

If that doesn’t work, please try to update the child actor’s position in the tick of the forklift manually and see if that works.
