# Materials

Randomly assign different materials to the instances to introduce variations.

It works the same way as applying a material to a component or a group in SketchUp: only the blank faces in the components will receive the material. If faces already have a material, their material cannot be replaced.

When using "[Render-only](https://skatter.help.lindale.io/generating#render-only-generation)", this feature is supported by V-Ray and Thea, but not Enscape at this time.
