Hi All, Afraid I need your help again. I need to put a spiral ID color line around a Spiral cable. Using a texture map would be the best way for me to do it the color of the cable, and ID line will vary. Any ideas? This would be no problem if the cable were straight, but can't figure it out with the cable being a spiral. Thanks again!

you might try this plugin http://www.pictrix.jp/?s=Px_Bezier&submit=Search Px_bezier

You can achieve this with blender, if you want.

134365

Add Curve:Curve spirals:Archemedian
134366

Set Fill: Full
Set twisting to Tangent and smooth to 100.
Set Bevel: Depth as wou wish.
Increase Bevel:Resolution.

Enter on edit mode (tab).
Select all with (a) if unselected.
Go to tools:Set spline type: Bezier.
Click on handles:Auto.

If you get any undesired twist, go to Active Spline and increase the Resolution, until there is no strange twisting.

Hit Alt+c to convert the object to polygons (mesh)

Enter on edit mode. Now you have the twisted spiral. You have to unwrap it.
Select one row and unwrap, if you don't know how tell me.

Another option is on lightwave, or another software:

Select all the large edges (select one large->select ring->select loop)
Detail Tab->Spin edge (wait.............)

Edit: If you make this option, be sure to make the wire with the correct number of rows and cols, if no, the twisting may be too heavy.

Don't quite understand this technique. Can you explain in more detail? Can't believe after all this time, Lightwave still can't easily do this!

Maybe I'm missing something essential, but if you only need it texture wise I would:

Either unwrap it at creation time of the spiral, or:
Select an Edge Loop wich goes along the spiral as a seam and abf unwrap the hole thing
Than scalke the uv and use the shear tool etc to stretch your uv maps accordingly
(use right mouse to define the area you want to shear in uv layout view)

hope this helps


aaaannnd.. edit:

you need to set the Range value in the shear panel to automatic, to get the handles working

PX Bezier rocks,
but you can also give this a go...

Yeah, I'd go texture map. I used UV Creeper (gotta do it in 11.6. It's broken in 2015 for MAC..... at least for me.)
Creeper gives a super clean result... as opposed to the more organic feel of ABF.
UVing gives you a lot of flexibility on wrap/spiral amount by skewing and stretching the UV as tischbein said.
The key is, on the initial skew make sure it's a full multiple of the UV space (i.e. a whole number) so the vertical tiling matches up.

another go (if going the 3D route that is)

yes indeed, UV creeper is a must have.

UV Creeper is not running in Lightwave 2015 on a Mac. Really don't another copy on my machine. Any other options?

so, you might wanna check out PLG UV,
https://www.youtube.com/user/erikalst/search?query=plg

then after UV mapping, skew the UV like JoePoe did.

should fix it (i think)

Doh!
Same brick wall. Not for Mac.

Try the ABF Unwrap. You might have to straighten things up a bit.

(personally, I think it's worth a 11.6 install....... Creeper is just that useful.)

Did it with Creeper. It does work in Lightwave 2015 for Mac

Once again, Thanks to all who helped! That UV Creeper is indispensable!

That's great news!

But tell me.... at first it didn't work and then it did. What did you do differently?
I'm still SOL. Even after reinstall.

Edit: Oh my.... Gawwwwwwwwd. Back up and running!!!!
I had become so used to hitting "ok" and seeing it appear in the UV space it never occurred to me that it was creating a new UV in the list and just not automatically displaying. Gotta go to the list and select. OR make an empty UV and Creep onto that. :foreheads.

I'm so glad I saw this post!!
