Makes sense from what you say. I probably should learn Substance Eventually, ironically however I managed to make a semi-clunky but working hue-shift with the 2.0 shark. Would be nice if I could do that again, but maaaybe I might also be able to do something different otherwise.
As for the head, I guess I preferred the more angular and less front-facing head from previously, buuuut if I don't figure out some kind of workaround, I could probably get used to how the newer heads look.
My main guess is that the belly would have to be re-weighted to allow for such bending, (one of Scarletkatt's avatars come to mind) I suppose I have no idea if you'd want to go back and edit it for the actual released model, but that's just my thoughts!
I digress either way, really oughta see and/or try out the newer model sooner or later in VR though, because aside from what I've noted, looks pretty darn good, that scaly look being one plus, heh.
