Hi TJ,
Thanks for the reply. Having seen your answer, I’ve actually done the same test again with a cube, worked out what angular velocity you would expect, using the formula for the moment of inertia for a cube, and UE4.10 complies exactly with the angular velocity you would expect, whereas UE4.8 doesn’t, so, as you say, what I am seeing is a bug fix, not a bug.
The issue I’m seeing in my game is almost certainly the same thing, it just happens to cause issues in my game, so I’ll just find some kind of workaround.
Sorry for the false alarm!
Thanks,
Jon
