Select Objects By Sub-Material (SOBSM) is a simple free script that allows you to quickly select all objects in your scene that use a selected sub-material from a Multi/Sub-Object material.
Unlike the native "Select Objects By Material" tool, which only selects objects by exact main (parent) material match, this script analyzes material IDs assigned to faces/polygons. This allows you to select objects by a specific sub-material, even when a Multi/Sub-Object material is assigned to the entire object and the desired sub-material is only used on a portion of its faces.
The script works with both material editors in 3ds Max - the Compact Material Editor (Medit) and the Slate Material Editor (SME). Select a sub-material in any editor, run the script, and all objects that use this sub-material (on faces with the corresponding ID) will be selected.
