Physic changes in 3.1

Unity Engine
1

I haven’t updated my game since 2.5 and just downloaded 3.1 on my machine. I noticed that my configurable joints physics are all off compared to how it runs on 2.5.

Is there any documentation on what was changed in the physics engine on 3.1?

Actually it looks like its flipped my TargetPosition.y where before I would set it to a positive number to increase the heigh of my object and now I have to decrease it to increase the height.

So before this would increase my height:
c1_bjointl.targetPosition.y = 0.1;
Now I have to make it negative like this to increase my height:
c1_bjointl.targetPosition.y = -0.1;

I’ll keep looking into how to flip this back, but if somebody can refresh my memory that would be good also.

Nevermind that’s not what the problem is. I’ll keep investigating.
