To be used as an NPC, these tentacles will need to be animated when it attacks. If this were purely for video, I'd just use the IKSpline, but given this is a game, bones are necessary.
I've already made a series of bones for the tentacles and skinned the model. But animating the creature and it's tentacles will be nasty without some form of control, especially given I need the tentacles to neatly shoot back inside the creature in a realistic way too. Not to mention the creature itself is subterranean and attacks by burrowing out of a hole that it will then sink back inside.
Ideally, an IK system that controls the entire tentacle would be nice, but with a number of mini-controls that allow me to influence the shape the rest of the tentacle behind it is taking. I just REALLY don't want to be controlling this thing with FK rotation of the bones.
Any links or advice is appreciated!
