Relink Bitmaps share by Colin Senner
Relink Bitmaps is a script to easily relink all missing files (Bitmaps, VRayMeshes, Mental Ray Proxies, VRayHDRI, IES, etc) when they change directories or when you move computers, check out the short video tutorial below for more detailed information. You can add frequently used folders, search sub-folders, find a specific texture or file and more. This script is completely free, but if it helps you save time, you can make a modest donation of $ 10 for the author.
After installation, the script can be found in Customize > Customize User Interface > Toolbars tab > Category > ColinScripts > Relink Bitmaps.
