Determine whether the glow originates from an Illumination map defined in the Scene Setup with the Illumination option, or on all bright parts of the model with the Luminance option.

#### Glow Intensity

How much glow.

#### Glow Radius

How much the glow spreads.

#### Glow Aspect Ratio

Higher value will create a more horizontal glow, lower value will be more vertical.

#### Glow Threshold

Controls the intensity threshold. Numbers close to 1 will have less glow.

#### Glow Threshold Softness

Amount the glow bleeds through the threshold.

#### Glow Tint

Lets you pick a color that will affect the glow color.

#### Tint Mode

<div align="left"><figure><img src="https://2307539615-files.gitbook.io/~/files/v0/b/gitbook-x-prod.appspot.com/o/spaces%2FVXPIT6wWK7VeTYMAHNYe%2Fuploads%2FXJui9d8YICEXjovaTa6r%2Fimage.png?alt=media&#x26;token=83e4ee7c-1ae9-4901-8fcf-011a43e6deb8" alt=""><figcaption></figcaption></figure></div>

You can change the quality of the glow from High to Low if you need the performance to be improved temporarily.

#### Glow Alpha Boost

Increases glow area source making it brighter.

#### Chromatic Diffraction

<div align="left"><figure><img src="https://2307539615-files.gitbook.io/~/files/v0/b/gitbook-x-prod.appspot.com/o/spaces%2FVXPIT6wWK7VeTYMAHNYe%2Fuploads%2FgLBkU5KqUF7Z0JjDtEPX%2Fimage.png?alt=media&#x26;token=b82c1b37-fcbb-43f2-ad4e-be2dbda9fad3" alt=""><figcaption></figcaption></figure></div>

This creates a "chromatic aberration" like glow around your object.

* **Intensity**\
  How much Chromatic Diffraction
* **Spread**\
  How much it expands out.
* **Soften**\
  Determines how soft or sharp the Chromatic Diffraction is.

#### Highlights

<div align="left"><figure><img src="https://2307539615-files.gitbook.io/~/files/v0/b/gitbook-x-prod.appspot.com/o/spaces%2FVXPIT6wWK7VeTYMAHNYe%2Fuploads%2FvlSYepSzUF4LymeblY4I%2Fimage.png?alt=media&#x26;token=b4f5744d-6cef-43d1-8867-daa172b0158e" alt=""><figcaption></figcaption></figure></div>
