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

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.
