Authoring using custom physics components
If you’d like to have more fine-grained control over your Physics simulations, refer to the custom Unity Physics authoring components demonstrated in the PhysicsSamples project. These custom authoring components are included in the package samples.
You can achieve the same runtime outcomes via the familiar and built-in Physics components that are provided with the Unity Editor through baking by default.
Import the custom authoring components
You can import the custom authoring components in your project as a package sample via the package manager.
To import the Custom Physics Authoring sample, open the Package Manager window (Window > Package Manager). Select the Unity Physics package, open the Samples tab, then select Import.
