A common mistake that is made is to set a node with a node with a localized paint map to "all fragments". This causes the entire mesh, not just the localized geometry, to react upon a collision event. In the animated example below you will see that the entire mesh begins to fall once the collision happens. | A common mistake that is made is to set a node with a node with a localized paint map to "all fragments".

Active
| type | bool |
|---|---|
| default | True |
| Simulates the motion of the body; otherwise the body acts as a passive collision object. |
Deformable
| type | bool |
|---|---|
| default | False |
| Track the shape deformation of passive (collision) objects. |
Active on break
| type | enum |
|---|---|
| default | off |
| indices | off : all fragments : paint/localized only |
| Normally when an object is connected to a simulator it reacts to gravity the moment the simulation begins.
