# Decals

> How to create decal and projector effects.

> The Built-In Render Pipeline is deprecated and will be made obsolete in a future release.
>
> It remains supported, including bug fixes and maintenance, through the full Unity 6.7 LTS lifecycle.

## Render pipeline information

How you work with decals and projectors depends on the render pipeline you use.

| **Feature name**         | **Built-in Render Pipeline**                                                                                  | **Universal Render Pipeline (URP)**                                                                               | **High Definition Render Pipeline (HDRP)**                                                                                          |
