.mt5 is a single material which you can apply to any material zone on any figure.

.mc6 is a material collection which has all the info about all material zones on a specific figure.

Example, my Dalek models have lots of material zones so they can be made to have different colours in almost every area without it affecting any other. Even the skirt panels are set up to have - if desired - alternating colours, as are the hemispheres on the panels. I saved a bunch of single materials in various colours which I can then apply to any of the zones as I want. These are .mt5 files.

Assuming I set up one of the Daleks in a specific colour scheme, say, off white body with gold appendages, hemis and collars (such as an Imperial or Necros Dalek)* I can then save the whole thing out as a collection. This is a .mc6 file. All these are procedural materials, btw; the matter of texture files is neither here nor there, it's the fact that there are many material zones included in the file.

*Yes, I'm a Dalek geek.
