Now that we have created some properties, let's actually hook them up to the shader so that we can use them as tweaks to our shader and make the material process much more interactive.
We can use the properties' values from the material's Inspector tab because we have attached a variable name to the property itself, but in the shader code, you have to set up a couple of things before you can start calling the value by its variable name.
The following steps show you how to use the properties in a Surface Shader:
