COPYPRO is a Maxscript that moves objects between 3ds Max files without needing to relink paths. It works with the V-Ray, Corona, and FStorm renderers, and has been tested on 3ds Max 2022, 2023, and 2024.
The script copies IES files, proxies, textures, RailClone objects, and Forest Pack trees, and can display the temporary folder size. The workflow is straightforward: open the library file, copy the object, then paste it into the target file. The developer suggests copying fewer objects at a time for better results, and copying library files into the temporary folder.
When a project is finished, save all assets externally and delete the temporary files. The script cannot copy textures with very long file names, and if it doesn't work on the first click, clicking two or three times may help. Version 1 was last updated in October 2023.
