Re: Mesh Format Viewer / Conversion.
-----------------------------------
Okay, I've found a way to list all the materials in an MMD's PMX/PMD file.

It is not pretty...

1) In PMX Editor, edit any 'non-Eng' material names and references to 'Eng'.
2) Ensure last material has text in 'memo' field. I add ##_place_holder_## to help search.
3) Export as CSV. Probably 2~~4 MB.
4) Load CSV into Wordpad.
5) Find the Materials section, which is some-where in the middle.
6) Carefully delete everything above and below.
7) Re-save the now slim-line CSV. Probably 2~~4 KB.
8 ) Open this in spreadsheet of your choice. Libre Office is *free*.
9) Compare to Materials list in PMX Editor. Note Editor counts from 0, Sheet from 1...

Am currently investigating CSU Comipo files. 
Comipo is NOT free, but happily imports OBJ and MQO models, and there are many, many community freebies. 
CSU is a proprietary format, totally mungs imports. Another issue is that it only has a limited colour palette, so apparently drops any named texture calls, converting them to palette references. $registered 3DOC can usually retrieve the mesh, but cannot yet find / read the palette references. At least it keeps the material groupings !! Situation akin to getting an OBJ without its MTL to specify what's what...
