Hi all,

How can i "draw" something in Lightwave, like a name, or a ribbon following a pre-defined path. I hav a client who asks to let a ribbon waving into the screen on a constant pathwith an end fix?

I tought of making an object, bend and twist and magnet it after a mapping, and then animate the transparency mapping. But I wander if I can do it with the geometry itself, like sliding in the geometry along a path

Sorry for my english, but I hope you get the point.

Regards,

Bob

Hi,

use splinetransform. You can find it on flay.
It's a great tool.

Or try this one: Fertilizer plugin (http://www.informatik.hu-berlin.de/~goetsch/Fertilizer/) .

Basicly you set up an image of the text in the backdrop, model your text as a seamless "ribbon" (I used the Magic bevel tool with 100% scaling on a simple box and then delete all but the front facing band of polys) and then create a wheight map with 100% weight. Apply the text as a planar transparency map with the same proportions as in the backdrop display options.Then just select the points from where the text/ribbon will come from (e.g. the beginning of the text) and give them a weight value of 0%. Go to Layout and apply the Fertilizer displacement modifier, select the weight map and press play. Voila!

Tnx,

Since our client wants several objects done this way, I'll try both possibilities.

Cheers

I've just done a waving ribbon that just moves up and down as it flows past the screen from right to left.

I cheated though because my deadline was very tight, and to be honest you cannot tell how it was done.

I just modelled a long wave, undulating however you need it, then in layout i just animated it moving past the camera, then duplicated and made the new one move slightly slower. It looked exactly like two ribbons flowing, and didn't use any dynamics/bones/cloth stuff that would take too long to calculate!

BUT if you need to make the ribbon spell a name or something, then go the other ways. It wasn't entirely clear exactly what you're after.

Good luck

I´ve created ribbons for a project with only bones and follower as a motion modifier.

http://www.cgsweden.com/Movies/VB.mov

The ribbons where created as a box with a bunch of segments, then in layout I created a couple of bones that all had a "follower" motion modifier applied. They where looking at the object, and traveled along its path but with a time delay. Worked very fast, and very simple since you had total controll over the object.

Hey,

Tnx for the bonething. All useful, especially when my deadline is tomorrow :)
Nice movie, but i need it to be more silky, more wavy. But indeed, by making an IK-chain in combination with a follower... I think that'll do the job.

Also tnx for the previous reply, but the plugins I found don't work for the MacVersion.

btw, maybe something for Yvan since he's also Belgian. I work on a little project between the hours. Ed Spacecadet. Just for fun, but it's more like a skillbooster for character animation and rigging, and also a little portfolio, in case I need one for the future. Maybe, if things go well I can start some little episodes.

Interested? Maybe I can send you a rigging-scene, so you can hint me some more. Mail me: bob.dekkers@telenet.be

regards

Bob

You can use a displacement on the world coordinates for getting the waviness you'll like. There´s a bunch of stuff that can do magic for ribbons, like lazypoints etc. Just nail down the rigging of the ribbons, and you'll good to go.
