We got pretty close to cracking them three months ago, here:
http://forums.kc-mm.com/index.php?topic=21212Unfortunately, I lost all my notes when I had to reinstall Windows and I can't get in touch with VILE to get his near-complete notes to finish the job. However, I do remember how .mot works. Think of it like a container format, similar to a character_motion.pac. There are pointers to each individual animation (tentatively called .tvca) that can be extracted. And these extracted .tvca files are very similar to chr0's, since TvC does use chr0's in certain weapons and articles. However, they're not the same. Format's set up differently. I just wish I knew how a chr0 header worked for this purpose...I'd really love to have TvC animations for Zero.
