You can create as many custom Physic Material assets as you need, and apply them to colliders in your scene.
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.
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
.
To apply a Physic Material asset to a collider:
Alternatively, you can click and drag the Physic Material asset file directly from the Project window 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.
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.
