Between bouts of ghastly melancholy, I've been investigating some of the MMD and other freebies.
Getting the mesh out of a PMD or PMX is fairly easy with my registered 3DOC. { Provided file not 'munged' !!} The textures are a different story. Like
Poser, PM* objects have UV-mapped textures in recognisable formats. Like
Poser, they also have auxiliary textures for transparency and reflections...
"The textures for .spa files are usually black and white, and the black will appear transparent. The darker an area is, the more transparent it will be. .sph files are often colored, and do not have the same transparency factor as .spa files do, and so usually appear darker."
Irfan View {free} did its usual magic and cheerfully announced that these .sp* files were incorrectly labelled BMPs. Sadly, 3DOC would not load a BMP when the PM* file asked for an SP*, so skipped that material's texture file, too. That left me with several un-textured OBJs.
After much Googling, I tracked down a {free} PMX editor with English menus. It also reads PMD files but, as yet, I cannot persuade it to *write* them.
After fumbling my way through the unfamiliar menus, I found where to edit textures. Changing eg metal1.sph to metal1.bmp for that dozen materials only took about ten minutes.
Re-saving the mesh as PMX, it now opened correctly. 3DOC exported it to OBJ + MTL, and some-one in the realm of
Poser will soon have a very smart pair of boots.
I'll need to use boot-stretchers, of course, of course, as Asian sizes run small...
