weird mesh scaling problem

I have made a rope with hinge joints.
I scaled x and z to make it little thinner. But now when my rope hits something bottom portion of rope starts to scale it looks weird.
Any1 knows whats problem

 

You might have your joints parented under each other like this..
--EmptyGameObject--
----Sphere
------Joint1
--------Joint2
......


Your hierarchy should look something like this.

--EmptyGameObject--
----Sphere
----Joint1
----Joint2
......

 

Heres what it looks like
Rope <Empty>
----Mesh
----Joint1
----Joint2

Tried lot of different combinations still doesnt seem to work

 

Oh, you are using a single mesh object? Im not sure how to work with that. You may need to look into skinnedmeshes
http://docs.unity3d.com/Manual/class-SkinnedMeshRenderer.html

Your mesh might just not have enough edges in the correct places.

 

It already has skinned mesh attached to it

 

I would avoid scaling. Scaling affects behaviour, if the scales arnt uniform you will get weird axis behavior...

think of it like this... if the scale is 0.5,1,1 then the x-axis will have physics applied at 0.5, while the other two axis have it applied as 1... so you would get less force/etc on the x-axis.

Im not sure this applies to joints, but since scale affects most of the physics system, I assume it probably does.
