thanks for those links, we're thinking along the same lines, as one of the other models i've been slowly working on for this project is an alien jellyfish.
here's a very early animation test of it's body and tentacles, but without it's dome. also the animation is quite robotic (stiff looking) so i need to do a lot more work on that:
the objects in the latest videos here on da, weren't originally intended to look, or behave, like creatures, although over the time i've been developing them i've realized they could be.
saying that, the concept for this one was that the large globule type object is being suspended by thick strands (as opposed to actual tentacles with tips to them) with the ends of the strands attached to the background (environment) object, seen here in a recent test:
A suggestion for an approach to tentacle animation: Represent each tentacle as a series of short bones. Animate the angles between the links, and arrange for a wavelike disturbance to propagate from one link to its neighbors. This is a good candidate for a scripting project....
thanks a lot golem, and as far as the rigging goes, that's the approach i've taken with the jellyfish tentacles, as opposed to the looped and strand objects in the above models which have only a few bones each.
here's a very short yt animation test showing how flexible my jellyfish rigs are:
each of those blue lines is a bone segment, so there are plenty of them, they can also stretch along the length of the tentacle to extend it, if need be.
re the wave propagation, i hadn't thought of applying that to the bones, but it sounds very cool, i'll see if i can do that, next time i'm working on the jellyfish.
any other suggestions you guys can think of, please let me know.
