Constraints glitchy / not replicating perfecly

Help and Feedback Scripting Support
#1

About 5 months ago i have been noticing weird issues with the constraints and i haven’t been able to fix them ever since. It affected every single constraint and caused them to either fling into space or shake rapidly and also replicate in a weird way.

Useful info :
The networkowner of every single block is set to the player
The creation is parented to the player its character

I have tried changing the maxTorque / maxForce / etc but it only helped a tiny bit.

I have a huge library of recordings regarding this glitch.

Please let me know if you know anything.

The library of recordings is irrelevant. They just depict an assembly that’s stuttering but there’s nothing useful here aside from one example that’s showing the result of the supposed glitch. Seeing the actual constraints and knowing how you interact with them would help much more.

The values are changed on the client side and what exactly do you mean with seeing the actual constraints? Do you mean the values?

#4

Still lacks the appropriate information I could utilise to help you solve your issue.

No. This.

I tried moving the plane to the workspace instead of the character and it did not help and i dont have any idea what could have caused this.
Also i have noticed something else too now, Whenever i anchor the nosepart of the plane only the nosepart freezes and the rest keeps on flying somehow while its bodythrust which is moving the plane.

If this is the case, that’s your issue, unless these objects are created client-side. I believe Roblox has implemented something into the Physics engine to prevent exploiters from fiddling around with things, namely attaching a larger hitbox to player models.

Try doing the physics calculations on the server and see if that changes anything.

This might also be related to Roblox implementing a new version of the PGS solver which solves a lot of problems, but also creates new ones in some rare instances.

I am quite sure its because of the new version of the PGS solver, Everything used to work perfectly about 5 months ago. :frowning:
Also its not possible to do these calculations on the server side since people will spawn in a lot of parts to crash the server.

Is there anything else i could do to fix this or atleast improve it?
