This page provides information about MaterialX support in Chaos Vantage.
## **Overview**
---
MaterialX is an open-source standard for representing shading networks. MaterialX shading networks can be used across different applications and renderers.
See the [MaterialX and V-Ray blog post](https://blog.chaos.com/materialx-and-v-ray-crafting-the-next-chapter-in-3d-creativity) for more information.
