i have 3 identical gameobjects, they use unity physics, have rigidbodys and sphere colliders. sometimes 1 object changes his physic to a lower gravity, moves slower to the ground etc...but all rigidbody variables are similar to the other 2 objects... i need a hint what i could inspect yet to find the problem of this behavior
i use unity 2.6.1 pro trial version
Things you can check: Are there other colliders somewhere, or are the colliders of these objects penetrating other colliders at startup? When exactly does this change happen? always with the same object? while interacting? Are there any scripts attached modifying the transform, or the rigidbody's velicoty etc? are the objects of unusual scale (say, >1000 or <0.01)? what are your game objects made of (meaning, is it maybe a mesh that maybe also has a collider somewhere in its hierarchy)? if you modify the rigidbody via script, is it correctly done in FixedUpdate() (as opposed to Update()?)
