Read time 1 minuteLast updated 19 days ago
To enable Rendering Layers for decals in your project:
  1. In the Project window, select a Renderer asset with a Decal Renderer Feature.
  2. In the Decal Renderer Feature, enable Use Rendering Layers.
When you enable Rendering Layers for Decals, Unity shows the Rendering Layers property on each Decal Projector.

Example

This section describes how to configure the following application example:
  • The scene contains a Decal Projector.
  • The Decal Projector projects a decal on the wall and the ground, but not on the paint bucket.
The following illustration shows the example:

In image 1, the paint bucket has the Receive decals layer selected. In image 2 it does not, so the Decal Projector does not project on the bucket.

In image 
1
, the paint bucket has the 
Receive decals
layer selected. In image 
2
it does not, so the Decal Projector does not project on the bucket.
To implement the example:
  1. Enable Rendering Layers for Decals in your project, as described above.
  2. Create a Decal Projector in the scene.
  3. Go to
    Project Settings

    ?

    > Tags and Layers. Add a Rendering Layer called 
    Receive decals
    .
  4. Select the Decal Projector. In the Rendering Layers property, select 
    Receive decals
    .
  5. Select the paint bucket GameObject. In the
    Rendering Layer Mask

    ?

    field, clear the 
    Receive decals
    layer. Now the Decal Projector does not affect this GameObject.
