What Gets Exported

LUT Files (.cube)

LUT files are collected and deduplicated from the following sources:

• Slot-assigned LUTs (A–T)
• Combination favorites (red heart) LUTs
• Input LUT favorites (yellow star) LUTs
• Look LUT favorites (yellow star) LUTs

The original folder structure is preserved, saved as {OriginalRootFolderName}/SubFolder/LUT.cube.

Preview Images

Folder Name	Content	Source
Favorite preview/	Combination favorite previews	Red heart combinations
Slot preview/	Slot assignment previews	A–T slots
Input favorite preview/	Input LUT favorite previews	Yellow star favorites
Look favorite preview/	Look LUT favorite previews	Yellow star favorites

Progress Display

Progress is shown in two phases: "Copying LUTs (X/Y)" followed by "Rendering previews (X/Y)". LUT file copying and preview image rendering are executed sequentially.

Notes

• If duplicate filenames are encountered, a _2, _3 suffix is added automatically
• If no LUTs are selected, a toast notification "No LUTs selected to pack" appears
