I’ve got a little guy with tentacles.
Anyway, I’ve done IK on the tentacles, and currently I’m moving them by dragging empties at their ends. However, this method has the unfortunate side-effect of not being able to properly position where, exactly, the bend in the middle of the tentacle should go. IE, I may want the tentacle to bend down, but it bends up, or it flops around in an animation between single keyframes.
Has anyone developed a method to move ropelike armature objects so that you can choose where the bends happen and which direction those bends face?
So far I tried adding an extra NULL bone in the middle of the chain and applying a track to to it; this doesn’t work. Blender seems to break the IK chain or to ignore the bone completely. The other solution I tried was to add a Track To constraint to one of the bones in the middle of the tentacle’s IK chain, but this … had undesirable results. ^-^
Here are two images. The empty target is hardly moved, but the test tentacle I made flips entirely:
Best case scenario I’d like to be able to add something near the hump which controls hump direction.
Any help on this?
Thanks in advance!
Edit: Incidentally, here’s a test animation of my character:
You need quicktime. See how that one tentacle cuts through his throat near the end of the animation?
