Adjust Rigidbody component solver iterations

Adjust solver iteration counts for individual RigidbodyA component that allows a GameObject to be affected by simulated gravity and other forces. More info
See in Glossary components to improve simulation results.

If a specific Rigidbody component in your sceneA Scene contains the environments and menus of your game. Think of each unique Scene file as a unique level. In each Scene, you place your environments, obstacles, and decorations, essentially designing and building your game in pieces. More info
See in Glossary requires higher simulation accuracy or stability, such as preventing jittering in stacks or ensure jointA physics component allowing a dynamic connection between Rigidbody components, usually allowing some degree of movement such as a hinge. More info
See in Glossary stability, adjust its solver iteration count individually. Increasing solver iterations uses more CPU time for that specific Rigidbody component. This targeted approach is more efficient than increasing the global solver iteration count, which would affect all Rigidbody components.

To adjust the solver iterations for a specific Rigidbody component, use Rigidbody.solverIterations on that specific component. This setting overrides the global project setting for that Rigidbody component only.

To configure the global setting for all Rigidbody components in your project:

1. Select Edit > Project Settings to open the Project Settings window.
2. Select the Physics > Settings tab.
3. Select the GameObjectThe fundamental object in Unity scenes, which can represent characters, props, scenery, cameras, waypoints, and more. A GameObject’s functionality is defined by the Components attached to it. More info
   See in Glossary tab.
4. Adjust the Default Solver Iterations value.
