Texture Relinker 1.0. Texture Relinker is a tool for finding, collecting, and restoring lost textures in 3ds Max scenes. The script analyzes the scene and shows the status of the used textures: which files are working, which are missing, which have already been found, copied, or relinked. Duplicates are displayed separately in cases where multiple files with the same name are found, and the correct option must be chosen manually.

Main features:
SELECT FOLDER - selects a folder for collecting textures.
ANALYZE SCENE - analyzes textures and their paths in the scene.
SEARCH FOLDER - searches for lost textures in the selected folder.
SEARCH PC - searches for lost textures on local drives.
FIX - links the selected found files without copying.
COPY - copies available textures to the collection folder.
RELINK - switches the scene paths to the collected copies.
RESTORE - undoes the last operation and returns the previous paths.
OPEN LOCATION - opens the location of the selected file.
SELECT IN SCENE - highlights objects using the selected texture.
DELETE COPIES - removes unchanged copies created by the script.
CLEAR - clears the analysis results.
SUPPORT - opens the author's support page.

How it works:
Click SELECT FOLDER and choose a folder for collecting textures.
Click ANALYZE SCENE.
If there are lost textures, click SEARCH FOLDER or SEARCH PC.
Select the found options and click FIX to restore the paths.
Click COPY to collect available textures in the selected folder.
Click RELINK to switch the scene to the collected copies.
If you need to undo the last operation, click RESTORE.
