Hi all.. Quick question, what is the best way to curve the chain (attached)?

I think you can do it with FX Hardlink, but it's been some while since I dabbled with it so it would be best for someone else to chime in there, though there is a video of William Vaughan's in his collection in the Tips and Tricks (http://forums.newtek.com/showthread.php?77002-Hours-of-Free-LightWave-Training-(24-Hours-)) section, fourth one down I think. If you have the Win32 (or OSX PPC) version of Modeler, you might consider using Pictrix's C_Bend (http://www.pictrix.jp/lw/Cbend/). You'll get slight curvature in the links though so it depends how accurate you need it to be. Because the chain is not contiguous you'll have to select the rest of the points as well after the initial two to determine the chain's length axis. I'll attach a .gif of me using it, not the most descriptive but it may be of some help.

You could also rig it in Layout and do a Saved Transformed.

I think Vaughan shows off the method that nickdigital is talking about. Give the chain some bones and let it sag under gravity in Layout, then save out the new shape to load back into modeler.

you might be able to use a clone plugin to achieve the same thing in Modeler,
though haven't tried it...

I'd try using DP Spline Deformer, part of Denis Pontonnier's excellent DP Kit, which is available from here: http://dpont.pagesperso-orange.fr/plugins/nodes/Additionnal_Nodes_2.html

Thanks, but I am looking to do this with no additional plugins. It seems I remember a magnet warp tool or something.

Yes there's a magnet tool in Model we which is really just the move tool with a falloff.

In the pure interest of using no plugins, could this work?

Basically it's Rail Clone, with two links following the contour of the curve. By selecting Automatic, the links "hook up".


I'd recommend trying what everyone else has said here first though as those methods are a lot more practical.

What about SplineGuide ? (native)

It'd be helpful to know: is this static, or animated?

Layout hardlink or Modeler railclone is the way i think...

The problem with bending or warping it is that it would change the shape of the individual pieces. With something like a chain or necklace you'd generally want those links to all be shaped correctly. I would probably set them up in Layout with IK and then save transformed.

yep, agree, the two links i posted fixes that though...

Yup, just sharing another option. I actually saw your video earlier today before I discovered this thread.

xswampyx's recent post in the sherlock holmes speedchallenge shows how to 'model' a chain using Bullet.
