Possible Puppet Warp Alternatives
First up is PhotoAnim 3D which is now free! It does skeletal animation and can create 3D objects from 2D photos. Basically mask what you want an object of and poof it's 3D (ish). It also has some parallax tools. One downside is it doesn't seem to export an alpha channel so you'll have to set a green background, export and key in HitFilm. The bones tools start @6:30 or so of this video
And this one covers creating 3D objects
The next one is Archipelis which is a paid product, 29 Euros, that also creates 3D objects from 2D images. I haven't tried the demo yet but from the tutorial it looks like it might make models that can be rigged.
