Initialize an empty set to store unique file paths

Iterate over all objects in the scene

This script is used to collect all of the external assets used in a Blender project and copy them to an "assets" folder in the project directory. The assets are collected from textures used in materials, linked libraries, and Alembic cache files. The script initializes an empty set, file_paths, to store the unique file paths of the assets. The script then loops through all objects in the scene, checking for materials and textures, and adds the file path of any textures it finds to file_paths. The script also loops through all scenes in the blend file, checking for linked libraries, and adds the file path of any linked libraries it finds to file_paths. The script also loops through all Alembic cache files and adds the file path of any cache files it finds to file_paths. The script then creates an "assets" folder in the project directory, and copies all of the assets in file_paths to that folder. If a file cannot be copied due to a permission error, the script will print an error message to the console and skip that file. The script then prints a report to the console that lists the number of files copied and their locations.

Let's modify it. After copying all files this script must replace the old file paths in all scanned blender entities with new file paths, located in the "assets" folder. And please reduce the amount of comments in the script

Here's the modified version of the script with fewer comments:
