Corona
 | Corona | This node creates light effects like glow and flare. |
This shader allows you to create light effects like glows and flares. To use it, just link the Corona Node to a Material Node that is linked to an Axis. The intensity of the glow is dependent on the perspective. Moving or rotating the Corona via the Axis node will modify the intensity of the glow.
The Corona shader offers three properties that affect the appearance of the light effect. The property Size scales the effect whereas the property Strength modifies the brightness. The last property Exponent defines the attenuation that takes place if the Corona rotates or moves out of view.
The default flare texture does not provide any alpha information. If rendered on a Render Target or if used in Ventuz over SDI output you will face unwanted alpha/key effects. Please use a custom texture with proper alpha planes to avoid this.
