Important: 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.
For more information on migration, refer to Migrating from the Built-In Render Pipeline to the Universal Render Pipeline and Render pipeline feature comparison.

In the Built-in Render PipelineA series of operations that take the contents of a Scene, and displays them on a screen. Unity lets you choose from pre-built render pipelines, or write your own. More info

, you can use a MaterialPropertyBlock to change material properties without breaking draw call batching. The CPU still needs to make some render-state changes, but using a MaterialPropertyBlock is faster than using multiple materials.

If your project uses a Scriptable Render Pipeline, don’t use a MaterialPropertyBlock because they remove SRP Batcher compatibility for the material. Use different materials for the different properties instead.

Warning: When you access shared material properties from a C# script, make sure to use Renderer.sharedMaterial and not Renderer.material. Renderer.material creates a copy of the material and assigns the copy back to the Renderer. This stops Unity from batching the draw calls for that Renderer.
