I need to rig a creature with tentacles for a game engine. The game engine doesn’t have stretchy bones support (only location/rotation). So I am thinking of the following setup:
A spline going through each tentacle, bones are parented into hierarchy, but not connected. This way they can slide on the spline, stretching the mesh.
I would need to be able to control length of the tentacle by dragging some control bone at the tip (which will also serve as a “foot”) and I would need to be able to “bend” the tentacle in several places to give it desired curvature.
It also need to be switchable IK/FK setup, and it should work when rotated at any degree (imagine octopus would be swimming with 6 degrees of freedom, so tentacles should behave properly no matter what pose octopus is in).
Most likely there should be pole targets, because game engine has IK system, and it requires having pole targets.
I’ve only done a few bipedal rigs, so I have no clue how to rig this one and if it’s even possible to get working.
Can someone help me, please ? Thanks beforehand.
