The Lens Distortion: Light Bloom controls enable light to spill over to neighboring pixels to create a glowing effect. Use the controls as follows:

• On: turns the effect on or off.
• Threshold: determines how bright pixels must be before light is allowed to spill over to neighboring pixels.

  Drag to the left to use a low threshold; all but the dimmest pixels will allow light to spill over, and the scene will look brighter.

  Drag to the right to use a high threshold; only brighter pixels will allow light to spill over. The glowing effect will not be as pronounced as one created with a low threshold, but will still be brighter than having no bloom effect at all.

• Intensity: controls the brightness of the affected pixels.
• Scale: controls the range of the effect; for example, the Large setting allows light to spill over to more pixels than the Small setting.

Bloom is not supported in ray tracing mode.
