Aka, Ninten tests the OP function of MMD 9.
Camus has got to be pretty ballsy to ride a very spiky dragon bareback. As soon as he gets his armor rigged, I'll make some sweet dracoknight pics.

Dragon by Valforwing (fav.me/d590cof) (huge overhaul* by me/Nintendraw), OP function tutorial by Trackdancer (fav.me/d7ih8r9).
*When I downloaded the dragon, it was fully rigged and poseable, but none of the bones appeared on the display (nor were they named properly), it lacked rigid bodies (and a saddle bone, which is how I seated Camus here), and had no facials. I fixed all of the aforementioned, AutoLuminous'ed its eyes (and gave it color change morphs), and gave it facials to allow for "speech" (aeo have different jaw-opening patterns, no iu), reduced fangs, and bipedal and wyvern modes.
