Greetings everyone! Recently I’ve come across an issue with the 6DOF Rigid Body Joint. When I add limits to the 6DOF joint; the constrained object “spazzes out” as if it is stuck in a collision. But this happens regardless of whether or not the object has collision enabled. I was wondering if anybody has an explanation for why this is happening. I think that I remember reading that it was an update to the bullet physics that broke it, but i’m not sure. Any help or explanation is greatly appreciated.
I tested in multiple versions of blender, and the problem doesn’t show up until 2.75. Versions 2.69-2.74 work fine, and versions 2.75-2.78a have this issue. Maybe a hardware issue? I run a NVidia 980ti and a i7 4770k if that makes any difference.
I also noticed that if I put the pivot at 0,0,0 everything seems to work fine. And the further away from 0,0,0 the pivot is: the worse the problem gets. If I put one of the values at 0.1 for example: the object shakes for a second or two before flying off.
I made a test file like yours and it works well.
Upload your test file. There must be something different in your file.
Did you upgrade the file or do you have done a new one?
