One-Step Copy & Relink combines two texture-management tasks into a single operation for 3ds Max. It scans the scene for all bitmap-based maps — standard BitmapTexture, VRayBitmap, and VRayHDRI — then copies the source files to a destination folder while relinking the materials to a different target folder using a new file extension.
This suits situations where you plan to batch-convert textures externally, for example converting TIFFs or PNGs to JPGs in a separate tool. The script copies the originals to a working folder but points the scene at the future location of the converted files, so once the external converter finishes the materials are already relinked, with no second pass required.
A typical run: pick a folder to copy the original textures into, pick the folder where the converted textures will eventually live, set the new extension, then click Process All Maps at Once. Run the external converter on the copied files afterward. The result is a portable texture set with relinked materials, ready for archiving, handoff, or further processing.
