# Material Op

> **Note:** **What is it about?**
>
> This page covers the **Material Op node** of the Scene Nodes system in **Cinema 4D**. It assigns standard, Physical, node or Uber materials to Scene Node geometry — the link between procedural objects and shading.

This Node can be used to create a connection between a Scene Node geometry and a material. This can be a standard material, a Physical material, Node material or Uber material.

If you want to edit the properties of a Node Material using this Scene Node interface you can us a Material Parametrization Node to do so. Note that special materials such as Architecture Grass and the Sketch and Toon material do not yet work in this Scene Node environment.

The connection between the shapes generated by the Scene Nodes and the materials is made via a Material Op Node, which is also responsible for projecting the material onto the object surface.
