# Add Base Gradient Material

Now that the base of our terrain is finished, we can add a first pass of material to it. To get a nice detailed material we will use the [Gradient material](broken://pages/ESklo2RZSwHRWGKws6te). A gradient material works by applying a colour gradient to a given greyscale gradient. The greyscale gradient will be created using the World Creators [distribution system](/reference/terrain/distributions.md). 

We start by adding a [Melt distribution](/reference/terrain/distributions/terrain/melt.md) to our material's Gradient distribution stack. You can now see the resulting mask. Next, we simply select one of the Rock Gradient presets in the Gradient material to apply a predefined gradient to the material. You can of course also create your own custom gradient based of colours or reference images.

To add even more detail, we will use a second gradient material masked with a [Roughness Distribution](/reference/terrain/distributions/terrain/roughness.md), which has a darker tone.
