This page gives some basic details about the Refraction Raw Render Element and how it is used in compositing.

 

## **Overview**  
** **

---

> ⚠️ To properly calculate the Refraction Raw Render Element, the Refraction Render Element must also be added to the list of render elements being calculated during the rendering process to properly determine all the refraction information in the scene.

## **Common Uses**

---

The Raw Refraction Render Element is useful for changing the appearance of refractive elements after rendering in a compositing or image editing application. Below are examples of possible uses.

 

## **Underlying Compositing Equation**

---

**Refraction Raw** x [Refraction Filter](https://docs-chaos.atlassian.net/wiki/spaces/VRAYNUKE/pages/110625531) = [Refraction](https://docs-chaos.atlassian.net/wiki/spaces/VRAYNUKE/pages/110625535)

## **Notes**

---

- To properly calculate the refraction information in the Refraction Raw and [Refraction Filter](https://docs-chaos.atlassian.net/wiki/spaces/VRAYNUKE/pages/110625531) Render Elements, the [Refraction](https://docs-chaos.atlassian.net/wiki/spaces/VRAYNUKE/pages/110625535) Render Element 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.
