## **Common Uses**

---

The **Raw Refraction Render Element** is useful for changing the appearance of refractive elements of a complete render inside a compositing or image editing application. For this example, the Raw Refraction RE and the [Refraction Filter RE](https://docs-chaos.atlassian.net/wiki/spaces/VMAX/pages/113575265) are used to tint and brighten the refractive materials in the scene. See how the render looks before and after compositing.

## **Notes**

---

- To properly calculate the refraction information in the Raw Refraction, [Refraction Filter](https://docs-chaos.atlassian.net/wiki/spaces/VMAX/pages/113575265), and [Raw Refraction Filter](https://docs-chaos.atlassian.net/wiki/spaces/VMAX/pages/113575303) Render Elements, the [Refraction Render Element](https://docs-chaos.atlassian.net/wiki/spaces/VMAX/pages/113575263) must also be rendered at the same time, even if it's not going to be used in the compositing process. Doing so enables all the refraction information to be included in the rendering calculations.
