Scaled bodies are unstable.

Postby pHySiQuE » Thu Jan 31, 2013 9:04 pm

If I create a box collision with the size 4,0.25,1 and drop the body to the ground it's perfectly stable.

If I create a box collision with the size 1,1,1, scale it by 4,0.25,1 using NewtonScaleCollision, and drop it to the ground it bounces around and gains energy. Here is a video:

It may be the same as this bug:

No I do not think this is the same bug,

I will recreate the same condition in the sandbox demos and see what it is. My guess Is that the inertia is no correct.
Is the code fragment at the beginning of the video, the code you use to setup that box?

I will try to recreate just just like that and see what is wrong.
