Okay, I have here this character I am working on:
http://doctorstopmo.250free.com/Skele/TridentCarrier1.jpg

He has lots of little jangly things hanging off of him (may not be very visible in the small render, but he does). When he walks, I want the jangly things to...well, jangle. I also want the chains to react correctly. Is there a way to do this in XSI 4? There are cloth regions also that I would want to apply cloth dynamics to.

Can anyone tell me how to do it please? Thanks a lot!

One option would be to use the create tail tool. Make a bunch of tails with just 2 or 3 bones each for each jangly doohicky. Attach them to the rig where needed and bind each jangle to it's own "tail". Then play around with the tail settings to get the desired result. I believe the "ears" in the advanced rig are the same thing. The belly system is another dynamic component in rigging that could be useful in other rigging scenarios as well.

Hope this helps for a start.

Hi,

The animation of secondary objects such as you've described is covered in depth in Volume 4 of the ACR (Advanced Character Rigging) series by Adam Sale.

It's available from 3dtutorial.com at:

See this link for more info:

Worth knowing about :-)

Cheers,

Joe

Hey, thanks a lot for the replies, guys! I actually found a tut that I think will solve some of the problems for the vertebrae dangling on the strings and such:

I actually emailed Adam Sale and he told me about the tutorial, which seems like it would be very helpful, but he also told me it's $49. I might check it out later.

I still need to know how to dynamically rig chains. Anyone have a tut on that?

I'd recommend his whole series. I used them to dive right into rigging myself recently, having never used softimage nor xsi before. They really helped in getting up to speed quickly.

do adam sale's tutorial cover cartoon character rigging? such as stretchy limbs , squash\stretch setup etc?

Hi Sheep....well sort of.

The tutorial is really aimed at realistic character rigging -- however, complex rig and muscle systems are described and a system of stretchy bones is implemented within. The point is that this series provides a very comprehensive education in the art of rigging which can be applied in neary any way that can be imagined depending upon the give solution you are looking for.

So, no the emphasis is not on cartoony rigs but rather rigs used for more realistic human motion. However, that is not to say one could not do that sort of thing with these rigs if they wished.

I hope this helps.

Cheers mate,

Joe

Excellent, well I'm happy you've found a solution that will work for you.

BTW -- Yes, it is true that the cost of this tutorial is US$49.00 per volume. This particular volume (volume 4) is over 7 hours long -- so we think it provides an excellent value for money, despite the cost. I should also add that this entire series (volumes 1-4) runs more than 27 HOURS in total length --now that's a lot of XSI rigging bliss :-)

Nevertheless, I'm happy you found a solution -- that's what it's all about.

Cheers,

Joe
