This page provides information on the Normals Render Element which creates a normals image from surface normals in the scene.

## **Normals Color Generation**

---

The Normals Render Element uses screen space to determine the colors in the render element. With screen space in the camera view:

The X axis runs left-right perpendicular to the camera viewing angle. This is represented in the Red channel of vrayRE_Normals with 1 being left-facing geometry and 0 being right-facing geometry.

The Y runs up-down perpendicular to the viewing angle. This is represented in the Green channel of vrayRE_Normals with 1 being up-facing geometry and 0 being down-facing geometry.

The Z runs forward-back to the viewing angle. This is represented in the Blue channel of vrayRE_Normals with 1 being forward-facing geometry and 0 being back-facing geometry.

## **Common Uses - Relighting**

---

The Normals Render Element is useful for changing the appearance of lighting in a scene in a composite without the need for re-rendering.

In the example below a relighting workflow is used at a composite level to change the lighting in the scene. Note that it does not create any extra shadowing. This example is exactly the same under the hood as that shown in the [Bump Normals Render Element](https://docs-chaos.atlassian.net/wiki/spaces/VMAYA/pages/111739314) page with the only change being that the Normals render element was used here instead of the Bump Normals render element.
