(My bad; I realized you wouldn't necessarily get the notification where I posted it before.)Okay, in FIM, a pony's rib cage seems to have two positions for the "shoulders": If the less than is the pony's back, the o is their rib cage and equals is their forelegs: Pinkie needs a hug " position puts the forelegs perpendicular, splayed out like a teddy bear: -0-On a real horse, their ribcage is a tall oval from the front, and their front legs are locked to straight down to the ground: in fact, their shoulders and biceps are locked tight against the rib cage and what we can see move separate from the torso is an arm from the elbow down: the "knee" in front is the wrist, and from there down to the hoof is the middle finger.A human, if put in a similar position to the horse, has a *wide* oval for the ribcage, and much more of the forelimb is free to move, but to do so, it sticks out to the sides.The FIM ponies have a perfectly round rib cage, and, as two dimensional drawings, can cheat their internal anatomy for effect.The SFM ponies, however, are locked into quadrupedal mode, and without a different rig/model for "Pinkie Needs a hug" there's a bump on the chest of the model where the "biceps" are locked against the ribs and they're moving the legs' joints in a manner they shouldn't. SFM Hug example: Note the harsh shadow on pinkie's chest.It's just a better effect, if you have a shot that needs it, to have a model designed for the wide, splayed hug, than try to make your "normal" model struggle to fit. Much like in Frozen; there's a scene where Elsa has a glove removed: for faster rendering, the first model had no skin for Elsa's hand, just a rig for the glove, and as the animation went on, they added the skin portion at the frame where the glove came off.In the end, it all comes down to what you're willing to put up with for a fan work. Don't get me wrong, what you have so far is superb... it's just a limitation of the SFM rigs that irks me, and I thought I might let you be aware of a potential problem that could turn "AWESOME!" into "meh" from nitpicky fans.But what do I know, I'm just some jerk on the internet.
