The basis is the same but like kasjorg say in this topic

It's very long to setup....
also it's just point interpolation but every parts have it's own layer !
the release of this animation have 2 objectives:
1- validate the character design (need your opinion about that !)
2- test an alternative animation "mecanism" (when the bone can't, interpolation can and vice versa)
The lesson i've take of this:
The result is fluid and doesn't look like cutout animation (often with bones), the interpolation add the "volume and natural touch" to the result !
Combination of bones and interpolation (with or without switch layer) makes moho a GREAT animation potential !!!!
2 more features misses:(it's my opinion !)
1-animatable "hide edge"
2-possibility to "pause" the interpolation (for switch layer)
