The FXAA (Fast Approximate Anti-Aliasing) effect smooths jagged edges in your content with minimal performance impact.
How it works
FXAA works by analyzing the image to identify high-contrast edges that appear jagged (aliased), then selectively blurs these edges to create a smoother appearance. Unlike hardware anti-aliasing techniques that require significant processing power, FXAA is a post-processing effect that works efficiently on any content.
This technique is particularly effective at reducing the “stair-step” appearance on diagonal lines and curves while preserving overall image sharpness.
Use cases
- Smoothing jagged edges in graphics and text
- Reducing aliasing artifacts in rendered content
Controllers
| Name | Type | Description | Range |
|---|---|---|---|
| Reduce Min | Number | Minimum reduction factor for edge detection | 10-1024 |
| Reduce Max | Number | Reduction multiplier for edge blending | 1-10 |
| Span Max | Number | Maximum span for edge detection | 0-25 |
Tip
The default settings (Reduce Min: 128, Reduce Max: 8, Span Max: 8) work well for most content. For more aggressive anti-aliasing, increase Span Max to 16-20.
