Light streaks
Intermediate Artist
Similar to the bloom effect, the light streak effect uses the result of the bright filter to make the bright areas bleed along a direction. It creates star-pattern beams from the light point.
Properties
| Property | Description |
|---|---|
| Amount | Strength of the light streak |
| Streak Count | Number of beams emitted by a bright point. The more streaks, the higher the performance cost. |
| Attenuation | How fast the light attenuates along a streak (0 for immediate attenuation, 1 for no attenuation) |
| Phase | Phase (angle) of the star-like pattern |
| Color Aberration Strength | Strength of the color aberration along the streaks.  Notice the streaks involve multiple colors (yellow, purple, green, pink). |
| Is Anamorphic | Simulates the behavior of anamorphic lenses, widely used in Hollywood productions.  The effect above is achieved by using two light streaks with a phase of 0, enabling anamorphic mode, and slightly distorting the bright pass result horizontally. |
