Rigid Body World ¶

Reference

Panel:: Scene ‣ Rigid Body World

TheRigid Body World is a group of rigid body objects,which holds settings that apply to all rigid bodies in this simulation.

When you add rigid body physics to an object,primary there is created a group of objects with default “RigidBodyWorld” name.Rigid body objects automatically are added to this group when you add rigid body physics for them.You can create several Rigid Body WorldCollectionsand allocate the rigid body objects with theCollections panel.

Rigid body objects and constraints are only taken into account by the simulationif they are in the collection specified in theCollection field of theRigid Body World panel in theScene tab.

Settings¶

Rigid Body World: Enable/disable evaluation of the rigid body simulation based on the rigid body objectsparticipating in the specified group of Rigid Body World.
Remove Rigid Body World: Remove rigid body simulation from the current scene.
Collection: Containing rigid body objects participating in this simulation.
Constraints: Containing rigid body object constraints participating in the simulation.

Simulation quality and timing settings:

Speed: Can be used to speed up/slow down the simulation.
Split Impulse: Enable/disable reducing extra velocity that can build up when objects collide(lowers the simulation stability a little so use only when necessary).Limits the force with which objects are separated on collision, generally produces nicerresults, but makes the simulation less stable (especially when stacking many objects).
Substeps Per Frame: Number of simulation steps taken per frame (higher values are more accurate but slower).This only influences the accuracy and not the speed of the simulation.
Solver Iterations: Amount of constraint solver iterations made per simulation step (higher values are more accurate but slower).Increasing this makes constraints and object stacking more stable.

Rigid Body Cache¶

Reference

Panel:: Scene ‣ Rigid Body World ‣ Cache

TheCache subpanel specifies the frame range in which the simulation is active.Can be used to bake the simulation.

Start/End: First and last frame of the simulation.
Bake: Calculates the simulation and protects the cache. You need to be inObject Mode to bake.
Delete Bake: Active after the baking of simulation. Clears the baked cache.
Calculate to Frame: Bake physics to current frame.
Current Cache to Bake: Bake from Cache.
Bake All Dynamics: Bake all physics.
Delete All Bakes: Deletes all baked caches of all objects in the current scene.
Update All to Frame: Update cache to current frame.

If you have not saved the blend-file, the cache is created in memory,so save your file first or the cache may be lost.

As other physics dynamics systems, rigid body simulation are also influenced by external force effectors.
