Transformer -- Consolidate all materials which use the same maps
A lot of Daz clothing has a TON of materials which all share the same UV mapping and same maps. You can collapse all these materials into the same without altering the maps or UVs, and this can usually eliminate about 90% of those materials (making it much easier to edit and/or change).
This is NOT collapsing to one UV (which then makes it impossible to use other material maps like Daz provides) -- it's just seeing what materials are exactly the same and making one material from it. It's included in my Blender plugin routines (which I'm editing and improving all the time) but I'll link to the dropbox code as well as a video showing the benefits.
