View Full Version : Dynamics vs. Character

Hello,

I was just looking to revive an old character of mine, a Zombie, and thought itīd be nice to have the stomach wobble and stretch loosely from under the ribcage. The "oesophagus", as itīs called in latin, is one long pipe, and in my model itīs from the jaw to the top of the hip bone. As Iīd only need dynamics in the lowest part, and need the rest of the pipe enveloped to the spine, I wonder how I could accomplish this in XSI.

Quickstretch seems not to work with skeletons.

Bone chains (asides of doing some astonishing offset) would probably work, but how can I apply a quickstretch/spring-net-thingie to bones ???

Cloth...Please, I donīt think Iīd have to go this far for such a little effect...


Please respond, Thanks,

-use softbodies on clusters, (downside only one parent can be considered so almost useless on a character if you wan to have different parts softbody differently and "correctly"even if you use collisons)
or
-manually make shapes or plot the softbady shapes and shape anim/mix them or drive that anim with expressions. Get different parts of body to react in softbody by parenting each time to a different bone then plot them and save the shapes(downside lots of work)
or
-use Chinnys great tut/method of softbodiyng a child of the bone then constrianign an envelope deformer to it(upside easy to set up, and can blend effect as it uses and envelope deformer, and extra envelope defomer can be used for other animation such as expression driven buldges when character bends. downside, hard to control on moe than cartoony character, the effect can be muted but not the added defromers, and very difficult to get it to work with with link shape deforms with ori, except for the envelope blend the effect is uniform, and shape is not considered so it look unatural) the tut is on Softimage.com for ver 2
or
-softbody a cage deformer. I have tutorial I started writing on this method(upside: shape is considered and the cage can be used to better manage link shape deform with ori setups, both cage deformer and softbody can be muted, effect can be more easily transfered to other characters, cage can be desgined to emphasize the various differences in parts of the body deform. downside more time to setup, overlap is more difficult to control, enveloe weights on main character must be off and transfered to cage which is not difficult but if cage is muted then weigths need to be put back using MIsners netview script and due to sefl promotion of my method I can't think of any more ;)

I'll try to post the tut soon
