# Metal Reflectance Node
|
|
|
|
## Description
|
|
|
|
Returns a **Metal Reflectance** value for a physically based material. The material to use can be selected with the **Material** dropdown parameter on the [Node](Node.md).

|
|
|
When using the **Specular** workflow, supply this value to the **Specular** block in the [Master Stack](Master-Stack.md). When using the **Metallic** workflow, supply it to the **Base Color** block instead.
