Relink Bitmaps repairs broken asset paths in 3ds Max when textures and other external files change directories or migrate to a new machine. It handles all 3ds Max supported bitmap texture types, Mental Ray proxy files, VRay proxies (.vrmesh), VRayHDRI files, and IES files including VRayIES. Later versions add support for Substance sbsar files, OSL files with an OSLPath parameter, and Redshift.
A command-line mode covers repetitive tasks and can be paired with Paul Neale's Batch It Max to run across a folder of max files. Configurable default user options cut down on repeated button clicks, the script checks automatically for updates, and it runs with a 250% speed increase over previous versions. The main window is resizable, and settings are saved to a Relink Bitmaps.ini file.
Listed here as free, Relink Bitmaps includes a donation link that removes the nag screen. Its licensing does not require transferring network cards or an internet connection, and the script collects or shares no data. It ranks among the more popular scripts on ScriptSpot.
