Cage,

I finally got round to doing a comparison between your "AP4 walk", old and new versions (nothing to do with walk_flip3). This is the output, after using them as walk blends at 100% in the WD. Seen from the front you have to look very hard to pick any difference. Seen from the side, there is more difference, the whole figure is shifted back in the new version, and there are differences in the amount of thigh and shin xrot, but not a lot. Personally I could not pick one as being better than the other.

Solid figure is the new version, yellow outline is the old version.

I will get back to walk_flip3 in my next post.
