Physics Settings
There are a few physics settings that can be configured and apply to the whole scene. They are found in the scene editor’s Settings extension under the Physics category.
Here's a closer look:
Tolerance Length / Tolerance Speed (PhysX)
If you are working with physics bodies that are either very small or very big, it is worthwhile to configure tolerance length and speed so that the physics engine reacts appropriately.
Tolerance length corresponds to the approximate size of objects in the simulation. This is used to estimate certain length-related tolerances.
Tolerance speed is the typical magnitude of velocities of objects in simulation. This is used to estimate whether a contact should be treated as bouncing or resting based on its impact velocity, and a kinetic energy threshold below which the simulation may put objects to sleep. For normal physical environments, a good choice is the approximate speed of an object falling under gravity for one second.
Tolerance length and speed cannot be updated in real-time. You must open a new session for them to take effect.
