assets as you need, and apply them to collidersAn invisible shape that is used to handle physical collisions for an object. A collider doesn’t need to be exactly the same shape as the object’s mesh - a rough approximation is often more efficient and indistinguishable in gameplay. More info

Several colliders can have the same Physic Material asset assigned to them, and you can set a project-wide default to apply new default settings to all colliders in the project.

Create a custom Physic Material asset

To create a Physic Material asset, go to Assets > Create > Physic Material. By default, Unity places new Physic Material assets in your Assets directory.

You can create as many custom Physic Material assets as you need. Physic Material assets have the file extension .physicMaterial.

Apply a custom Physic Material asset to a collider

To apply a Physic Material asset to a collider:

  1. Navigate to the target collider’s Material property.
  2. In the Material property field, select the picker icon.
  3. Select the Physic Material asset you want to use.

Alternatively, you can click and drag the Physic Material asset file directly from the Project windowA window that shows the contents of your Assets folder (Project tab) More info
See in Glossary
onto the target collider’s Material field.

Each collider can only have one assigned Physic Material asset at a time. You can assign the same Physic Material asset to multiple colliders.

Set a custom Physic Material asset as the project default

You can use a custom Physic Material asset to replace the project-wide default settings. Unity applies the project-wide default settings to any collider that does not have an assigned Physic Material asset.

To change the default Physic Material values: 1. Create a Physic Material asset and configure it to the default settings you want for the project. 2. Go to the Physics Settings (Edit > Project Settings > Physics). 3. In the Default Material property field, select the picker icon. 4. Select the Physic Material you want to use.
