Create and apply a custom Physics Material

Create and configure a Physics Material to define a collider's surface properties, and apply it to a collider.
Read time 2 minutesLast updated 20 days ago
You can create as many custom Physics Material assets as you need, and apply them to colliders in your scene.
Several colliders can have the same Physics 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 Physics Material asset

To create a Physics Material asset, go to Assets > Create >
Physics Material

?

. By default, Unity places new Physics Material assets in your 
Assets
directory.
You can create as many custom Physics Material assets as you need. Physics Material assets have the file extension 
.physicMaterial
.

Apply a custom Physics Material asset to a collider

To apply a Physics 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 Physics Material asset you want to use.
Alternatively, you can click and drag the Physics Material asset file directly from the Project window onto the target collider’s Material field.
Each collider can only have one assigned Physics Material asset at a time. You can assign the same Physics Material asset to multiple colliders.

Set a custom Physics Material asset as the project default

You can use a custom Physics 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 Physics Material asset.
To change the default Physics Material values:
  1. Create a Physics 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 Physics Material you want to use.
