Disable and strip the physics integration SDK from your project to meet specific performance or feature requirements.
Unity supports a number of versatile and performant physics engine integrations. However, if your project doesn’t require physics simulation, you can disable and even remove the physics integration entirely from your project. This can result in a smaller build size for certain build platforms and more optimized resource usage. When you do, all physics-related functionality, such as physics APIs and components, no longer work in your project.
If you enabled Strip Engine Code in Project settingsA broad collection of settings which allow you to configure how Physics, Audio, Networking, Graphics, Input and many other areas of your project behave. More info
See in Glossary, you must set 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 SDK in the Physics Project Settings None to strip the code of all built-in physics integrations alongside other engine code.
