Under the hood, Mari passes around a set of four numbers along a connection between two nodes. The Constant node is solely used as a set of four numbers grouped under one slider, see Constant Node Properties. You can use the Constant node in conjunction with nearly any node, it depends on your workflow. For example, you can use it to adjust the position or color information, or you can use it as a number to change the value of another node, for instance, a shading node.

Constant: Node Graph Workflow Example
In this example, we are going to use the Constant node to make changes to the Glossiness channel of the BRDF shader.
| 1. | Create a Color node and connect it to the Diffuse Color input of the BRDF node. |
Connecting a Constant node to the Diffuse Color input of the BRDF node to texture the object
| 2. | In the Color node's node Properties, change the color to red. |
The object is now red.
The Color node gives a red texture to the object.
| 3. | Create a Constant node and connect it to the Glossiness input of the BRDF node. |
Creating a Constant node and connecting it to the Glossiness input of the BRDF node.
Notice how moving the Constant slider of the Constant node (see Constant Node Properties) changes the Glossiness of the surface.
