Selecting & Sorting

Selecting and Identifying Ghosts

Before modifying a ghost, you first need to identify which ghost you want to adjust. Since a lens system can generate many ghosts, Flares OFX provides tools to help you find them easily.

Ghost Isolation

The Isolate Ghost feature renders only the currently selected ghost and temporarily hides all others.

This allows you to:

• Clearly see the shape and position of a single ghost
• Confirm that you are editing the correct one
• Avoid visual clutter from overlapping artifacts

Ghost Highlighting

The Highlight Ghost feature colors the selected ghost using a distinctive, stand-out color.

This makes it easier to:

• Locate a ghost within a dense flare
• Step through multiple ghosts visually
• Compare ghosts without hiding the rest of the flare

By combining isolation and highlighting, you can quickly cycle through the ghost list and identify the exact ghost you want to modify.

Sorting the Ghosts - Why Sorting Matters

Ghosts are relatively expensive to render, especially in complex lens systems where hundreds of ghosts may be generated. In most cases, only a small subset of those ghosts contributes meaningfully to the final image.

To improve performance and focus on what matters visually, Flares OFX provides a Sort Ghosts feature.

Sorting by Intensity

When you click the Sort Ghosts button, ghosts are reordered based on their intensity, from brightest to dimmest.

This allows you to:

• Identify the most visually important ghosts
• Limit rendering to only the most noticeable artifacts
• Reduce render cost significantly

For example, after sorting, you might choose to render only the first 10 ghosts, which are typically the brightest and most visible, instead of rendering hundreds of low-impact ghosts.
