Box components jerks/twitches

Hey guys!

I have a problem that I can’t understand the reason to happen.

I had skeletal mesh as a root component. The movement of the pawn is defined by lerping the value of physic linear velocity with the speed vector and setting that as the physic linear velocity of the mesh. It worked fine but I decided to switch the root component to the box component and attaching the mesh to it.

When I did that the pawn started to jerk frequently. I tried to play around with the physics (used AddForce, AddImpulse and so on instead of setting the physical velocity) but no luck. Then I put all of the objects to the PostPhysics tick group and it didn’t work either.

When I switch back to having the mesh object as root it works fine.

Do you know why it happens?

Thanks!

Nevermind I’m a dumb-dumb. I accidentally enabled spring arm camera lag. Don’t be stupid as I am.
