Go to: Related nodes. Attributes.

This node contains the attributes for the rigid solver. The attributes of the rigid solver control the accuracy of the rigid body solution along with some global attributes such as friction, bounciness and caching. The user can change the collision tolerance (a delta distance at which two rigid bodies are considered to be "in contact" with one another) and step size (the step the rigid solver takes to determine the rigid body solution). Decreasing either of these attributes will cause the solver to run slower but more accurately. This node also controls the display of annotations such as the center of mass, velocity and constraint indicators.
