The first stable release of the Matlib Manager is out ! This script allows to save a matlib from a scene or a selection, and to save which material goes with which objects (name-based). Then it can be easily/automatically reapplied. It has been initially created for the Cosmic Love production, but this brand new version have been entirely recoded, that’s why it’s an alpha version: I’ve done a massive debugging, but I’m waiting for feedbacks to set it officially to a « stable status.
Here is the dedicated page, with usage and installation instructions: onectin.fr/matlib-manager.
