vrayRE_Normals is a render element that stores the camera space normal map using the geometry's surface normals. The Normals Render Element is useful for adjusting lighting in the composite. For example, the red, green and blue channels can be adjusted in compositing software.

Bump maps are not represented in this render element; to include bump maps, use the Bump Normals Render Element.

When Normals Render Element is saved as a separate render channel, its output value is kept between [0;1] range; if saved as a multichannel .exr, its output value is in the range from -1 to 1.
