Dragging Physics Objects is Jittery Until Stepping on Them

You can write your topic however you want, but you need to answer these questions:

  1. What is the issue? Include screenshots / videos if possible!

When I start dragging a physics object, the movement is very jittery. But after my character stands on the object, it becomes perfectly smooth. I enabled Are Owners Shown and the green outline means it belongs to the player.

I am not using Roblox’s built-in drag detector. It is based off Starmaq’s object drag post, which uses AlignPosition.

  1. What solutions have you tried so far? Did you look for solutions on the Developer Hub?
    There is an AlignPosition property RigidityEnabled. It does gets rid of the jitteriness, but makes the movement of the object less natural. You also can’t fling the object but you can work around it by using RunService and do
velocity = (object.Position - lastPosition) / dt 
object:ApplyImpulse(velocity * object:GetMass())

Just wondering if anyone has ran into this issue before or knows a fix.
Any help would be greatly appreciated.
