Hi, thx for giving this early access, love you Epic.
Here the first result of my test with Chaos Vehicles Plugin.
Just create the project with the Vehicles Advanced (BluePrint), answer yes when Unreal 5 ask for updating the project on start.
And hit play … The car land on the floor, the suspension still are working, the camera inside outside, the sound etc…
But, the wheels do not turn left and right and the car do not move at all.
I have two computers desktop (not laptop) and i do the same on both.
It is simply never working in my older computer (as describe upper).
It is working in my new computer, but with no constant behaviour (see below).
On the new computer:
The same project can work or not work during the same session. Escape and retry to play can randomly make it work.
The car can also suddenly stop working during the play.
The front wheels stop rolling at some point during the decelerate (not brake) at some range speed even if they can turn left and right.
The torque have some loose of power.
The reverse as brake option can simply not work on some car and work on other.
The car can freeze in the air during a high jump and just fall straight way.
Not really chaos related but it happens to.
The sound stop playing at high speed.
Just to add in info:
UE4.26 chaos preview3 work seamly on my both computers.
I don’t get it working with my old computer, UE5 Chaos Vehicles plugin simply don’t work, the car never move.
And to be precise, i was just add the info to confirm this pc can handle chaos because it is working fine with UE 4.26 Chaos preview 3.
And even 4.26 the credibility of the behaviour is matter of taste i can say.
UE 5 early access Chaos Vehicles plugin work only with my more recent computer, but with all the strange behaviours described in the first post.
That’s it, i have stop to try, Chaos Vehicles plugin is not ready yet to do any relevant vehicles gameplay, except for totally inaccurate gameplay can be cool.
I don’t know if that can solve your problem, but you too the vehicle is not moving, go to the plugins management, uncheck “chaosVehiclePlugin”, restart, go back to plugin management and check again “chaosVehiclePlugin” and restart. Et Voila! For me it work at least.
I am trying to debug this to find out why the vehicle doesn’t move and I had a breakpoint in the car initialisation. Looked through the block of code and couldn’t see anything wrong, so hit F5 to continue.
And suddenly everything worked. The car actually was pretty good , which was a surprise.
Removed the breakpoint, and everything was broken again.
So my guess it’s a thread timing issue
Oh and by the way, don’t try to disable the chaos vehicle plugin. Makes the editor crash
I am also receiving issues with Vehicles(But custom vehicle using physics constraint)
It seems as if the constraints (angular and linear) does not lock It is always on free.
Do you think it is also part of thread timing issues?
What I am seeing is that the vehicle component is throwing async inputs at chaos, and chaos is NEVER supplying any output
The chaos vehicle component processes the async que and moves objects about, but they are all empty
/* READ OUTPUT DATA - Access the async output data from the Physics Thread */
void UChaosVehicleMovementComponent::ParallelUpdate(float DeltaSeconds)
if (const FChaosVehicleAsyncOutput* CurrentOutput = static_cast<FChaosVehicleAsyncOutput*>(CurAsyncOutput))
Thanks Paul can you some how push this to the Epic guys, personnally i don’t really want to go the github+compile route so i’ll have to wait for a update on the launcher version if it doesn’t take to long
