Hi,

Image

Here is latest version of Knit Strand compounds, I called this one "Knit Strand Pro" :).
What's new:
1: better distribution, now strand size always fits between neighboring strands, whatever deformation is used.
2: lighter in render time: strand segments are generated sparingly, also there are built-in strand resolution attributes.
3: default is spread in X-Z plane. NURBS surface is optional, strands will fit to NURBS only if NURBS is connected.
4: diagonal distribution, like common fabrics

Should be much faster than old one. Fitting od strand size rely on simple, 'parallel' computation, not on geometry query by distance.

For later use, export the "Knit Strand pro" compound, using "embed internal compounds" option (if you don't already have Kristinka Hair 3).
Compound should reside under Particles/Strands.
In almost three years, I've found these nodes doing the best by converting the strands to mesh, or even better as texture generators.
If you try to render from camera, included in setup, you'll see something like this - displacement/bump of some kind of denim.

I'm surprised nobody commented on this yet. Looks pretty interesting. Will have to give it a try.

Thanks Mathaeus!

Hi,

First - amazing stuff, love the concept and execution. I have the Pro compound setup and tested and it works great. I was hoping you might have an updated workflow for converting the strands to a mesh?

I have gone over the older posts but have not been able to reproduce the steps, mainly because I can't seem to find the mt_ice_StrandExtrude compound anywhere (despite having Kristinka 3, the old HM Strand Nodes from the ice tutorial, searching everywhere). I also have extracted "Knit Strand Prepare MT_Extrusion" but that doesn't seem to work either. Any guidance would be deeply appreciated and thanks again!

-Nick B.

Thank you guys,

there is an update on same link, new one has built-in attributes for MT/Melena strand extrusion. Of course you'll need appropriate version of Melena installed.
If so, procedure should be: select point cloud, run "create ICE strand extrusion" or like.
Theoretically, out of the box strand extrusion from v 2012 and more, should work too. Didn't tried this, anyway.

cheers

knit the strand in action /with hand tweaking afterwards/

Works like a charm - this is really awesome. Extrusion working, color working, nice stuff. Thanks for sharing it and I am off to put it to good use.

PS - Origin, sweet stuff - very cool use. Any tips for those of us just getting going with it?

Thanks,

-Nick

sorry that was done some time ago so I dont really remember details.
I think the most annoying thing was nurbs mesh manipulation cause of how lame nurbs in SI are (workaround create nurbs from polymesh and manipulate the source polymesh instead)
as for extruding strands I think I used Fabricios or Guillaume's ice compounds.

I am going to give it a crack this week. Will see what I come up with. Thanks again!

whats the procedure if there is one, to change the pattern to look for example like wool or another type of fabric similar?
thanks

hi,

there is no built-in procedure for wool. Which wool, btw. It's build on what's called a 'modulo trick'. This method, occasionally, allows the enough pleasant creation of simple patterns, result of this method occasionally reminds to something from real world. For something more complex, I think the best way is manual creation of entire pattern, leaving only variations to ICE, but this isn't a short procedure, anymore.

cheers

ouch got it, thats bad couse i have some animated cloth that where screaming for your compound :D

only thing is that cage deforming the nurbs (with your pattern) to the polymesh with syflex seems not working, i guess that your methode of creating the cloth from nurbs then exporting it to mesh and add that as a shape key might be the only way.

thanks for the info will try something out.

latest setup is able to render the displacement/bump texture - that's what I would do when it comes to cloth.

It appears that you got the strands to form diagonal patterns. How is this done? I can only seem to get them horizontal and vertical.
