Help Bone: Bending around obstacles

[josemendez]

My goal is to allow the tentacle to deform around walls with an ik constraint that's controlled by a player. i.e. if my tentacle flows around a corner, it should retain it's shape as much as possible while bending to accommodate the corner.

How are you implementing this IK constraint?

I've tried only turning on bending, but this doesn't work well. Is this effect achievable with Obi Bones?

If you disable stretching (stretch/shear constraints) then bones will stretch infinitely. Note this isn't the same as disabling "stretch bones" in the ObiBone component: this will simply keep the original bone scale/length intact, but the simulation will still constrain the length and relative position between particles.

The effect you're after is definitely doable using bones.

I feel like I almost want to put a rope in the tentacle and just make new control points when it rounds a corner.

Ropes won't work for this however, since they're unable to keep their rest shape and they don't model torsion. Both are required for a bone chain.

I've included my example scene, thank you in advance!
