Plask.ai Mocap - Initial Look
First look at Plask.ai.
From other videos around, and from these results, its safe to say that you won't be able to get feet tracking from this application. As for overall accuracy, its tough to look at for this, since this footage is so old. Ill have to shoot some more usable footage at another time to gauge it's effectiveness.
Not bad for quick upper body character animation though, it was very quick to use and download.
