Finally, in frame 15, I apply another partial pose - for his left forearm this time - but I do it via the Poser Python method, which is the same as the prpc code that P3dO would use. I know, because I took my Python from prpc. ;)

Although only Simon's right forearm pose was changed, you can see that keyframes have been set figure-wide as before.

Digitani isn't claiming that things are posed that shouldn't be; rather that the setting of keyframes on every actor is a problem for an animator.
