D5_MultiSub_MatID

This tool helps D5 Render and 3ds Max users create materials that support a multi-texture / randomize workflow. Because multi-texture handling in D5 is limited, the script acts as a practical workaround in 3ds Max: it collects the selected base maps and builds a Multi/Sub-Object material containing all of them, with optional rotation, mirror, and UV-offset variants added as extra sub-materials.
