Hi!

Which is the absolutely fastest way to make cables wire up themselfes into given positions, a typical jack in jakc out behavior.

I have tried Worley´s Dangle plug in their Polk Collection but that´s too limited.

I have tried Lightwave´s bone and IK setup but that´s hard to master since the cables swing around as they had their own life when dragging the end nulls.

Any suggestions?

have you tried ikboost
for fast 'dirty' things like that it's the best solution imho

If youre on a PC, this one is also quite good.
Its a spline deformer. The nodes are nulls and can have
standard IK, IKB etc applied to them.

Never tried that... but it´s hard to get any good info about IKBoost in LW9.6.

Anyway I did find this one instead. It´s by Proton and it includes dynamics:

It´s called:
Animating a hose that is connected to an object on each end, It can be found under dynamics at this link:

If you don't mind using bone chains download "Plugin Which Curves Bones Like A Spine"

from this site: http://homepage2.nifty.com/nif-hp/index2_english.htm. It's the best spline IK I've used for Lightwave.

The advantage of shift spline transform:
1. The nodes are nulls thus can be parented to other objects, work with IK or IKB wich also means you can apply dynamics to the nulls.
2, Works with bones
3, Works with weight maps
4. You can apply multiple instances to an object.
5. Allows the objects length to be animated using an envelope
6. Allows the object to be animated along the spline using an envelope.
7. Since the controllers are nulls they can be controlled using expressions, motion modifiers etc etc.

SplineGod and JasonWestmas I´ll get back to you with some questions tomorrow when I have tried to understand the stuff you related to! Thanks a lot for your effort!

Here´s a question during the time! William Vaughan wrote a tutorial on this. But I can´t see if he placed the different object on different layers or if they´re all placed in one. The video doesn´t tell, anyone who can figure this out for me?

Hi SplineGod!

This is all it says: Shift Spline Transform. Like the spline deformation tool for layout, but on steroids. Download SplineTransform...

I admit I am not too much of a tech guy but this doesn´t say me much of how to use this plugin. Isn´t there any explanations more than this at all I have to forget about it.

Do you have any knowledge of it please guide me a bit so I can evaluate if this plug can do the job! The text below sounds great but I can sure need some guidance to get there. Do you have any instant solutions I would be glad to learn more!

JasonWestmas!

I must say this was a hell of a pluging for creating snakes under water or anything like it. What a great plug!

However in this special case, I wan´t to create a cable that is being plugged into an electrical outlet at the same time it´s rear end is being connected to another socket. I cannot see how this will be possible with this extremely nice plug-in since with this you use the rear end to puch the object forward?

If you have any suggestions I would appreciate it!

Heres a rig for a simple hose.

SlineGod you are awesome! I´ll check it up at once...

Hopefully I get it by seeing it, but if not? Well, the story is to be continued at least for a few more replies if you don´t mind!

I might owe you a Guinness, Pint, Lager or whatever if I ever get to NZ with a beer hose! :thumbsup:

Additional question:
When adding a sequensal of bones (128) to a quite long cable Lightwave almost freezes itself whatever I try to do in it! Is this a bug or what?

Additional answer:
A link to an answer I found in here and it hurts a lot because I understand this means that I have to cut my cable to please Lightwave´s engine!

Too bad that Shift Splane Transform is not 64 bit though..

What Ive done in the past is to use SST on 32bit LW and then mdscan it.
Then I can switch to 64 bit and use the mdd file.
