Kristinka Hair 3.2Author: Anto Matkovic
The July 2014 update is another big one introducing new nodes like »Fit NURBS«, »Curls advanced«, »Curvature Amplifier«, »Grouping in Form« »Follow CurveList« »Stretch Hair« »Hair Filler Rounded« — for a full description see the si-community thread and the updated documentation.

The Kristinka Hair toolset is a new and unique way to set up, style and simulate hair using ICE nodes. A set of fully customizable ICE nodes Scalable, from only a few basic compounds for building basic hair, to very complex structures. Hair styling that always considers the whole shape of the hair. Styling works well for short and for long hair. Unlimited hair length, unlimited number of hair segments. Automatic, procedural generation of details - always with full control. Locks, clumps, curls, turbulence, are created by ICE compounds Additional modifiers, like cutting hairs by external geometry, constant strand length for key frame animation, resampling and subdividing strands, morphing with another hair, modulating hair's distribution over emitter, so user can increase density on most visible areas Full support for the Sofimage's built-in Strand Dynamics Framework simulation engine. Only factory ICE nodes were used, it should work nicely with any Softimage version from 7.01 on.

Other media available: Version 3.1's online 'first steps' tutorial. si-community user Bronco67 has created a video introduction for an earlier version available here. Also: A rendering tests thread, a TV ad by PsyOp featuring Kristinka Hair.

In case you want to apply kH3 nodes and dynamics on top of strands that were not generated by kH3 itself, here is a setup to enable that.

Hi Mathaeus
Just a quick question. Am I able to use advanced curl node on the syflex model example? I copied and pasted the adv curl nodes from the model example into the Syflex done model example master point cloud but it does not affect the hair.
John
PS
Do you find that the Syflex method gives better results than the previous dynamics example you had provided?

It should work, but it wants a bit more of strand segments, than count in this example, to do something visible, using it's defaults. Let's say instead of 'kh clumps and locks' node in example, try to put "kH subdivide strands". After this one, 'kH Curls Adv'. It uses the strand segments instead of relative length, this is to be able to do as much more turns with less points. One turn is 8 points by default.

I wanted to share some work I completed with Kristinka, and thank you again for the latest update. It makes light work of hair / fur.

Curls Advanced is working quite well for some Dreadlocks!

I also did some work for AMD this year. You might see Kristinka in your local electronics store.

I completed a few other characters this year. But cannot show them just yet.

Thanks so much for all your hard work. Kristinka gives our studio the most control over hair style compared to any other hair solution.

Thank You, Master izze ! As a matter of fact, I sow this pic somewhere, didn't know there's izze somewhere around :). Izze, when we are already on subject, should I do something with this Curls - to - dreadlocks compound, really haven't dreadlocks in mind when made this thing.

Thanks for all the feedback. I really just posted those images to point out how much I appreciate all the work Anto has put into these compounds. Sorry to de-rail the thread. I had a few people ask for a breakdown on the setup for AMD's Ruby image. I did put something together and will post a link as soon as the boss approves releasing the images.

Anto:
I am extremely novice in ICE and am probably doing a lot of things counter to you designs. I will just explain what I have done, and you will probably know of a better way to accomplish the same results.

As far as the dreadlocks go. The only thing I really "modified", was adding modifiers to only the strands effected by follow curves node. It got pretty difficult to see clearly the results of Curve Adv when it was applied to the whole pointcloud.

I had difficulty getting the curls to start close to the start of the curve. I had to put two points very close together to eliminate the InBlend. But if I knew ICE better, I could probably have modified that compound.

I am also duplicating the pointcloud to get the proper look for "loose" strands. Using Hair Tips node in combination with the very old Hair Length node. The one with Factor and Factor Minus. But this is still very much WIP and I will probably be able to eliminate the second pointcloud.

The last thing I am trying to accomplish is colored thread to wrap a few of the locks. Using Curl Adv again. It would be amazing if there was a way to push strands outside of strands. Maybe there already is :)

But again, these are really really amazing compounds you have created! I have no actual production stopping problems with them. Thank you so much !

Here is the pointcloud for the dreadlocks. Remember its still very WIP. :)

That's amazing Izze! thanks for that great insight!

And Otto-Rig also looks really quite advanced (& easy)!

do you think it might potentially be released (or made available for purchase despite circumstances) at some point?


By the way, I passed by ElementX last year when I was over at Janimation (2 seconds away :] )

Seemed like really a neat place!

Nevertheless, Nice Work!

(yep, great stuff makes for lots of exclamation marks!! :] )

I hope I'll post some improvements, this weekend, here. Here's short plan:
1: a bit better visualizing. I know you already know, it's possible to get strand color per 'form' node, 'chunk' and so on, using 'kH randomize node;. Anyway wouldn't hurt to add a sort of 'diagnostic mode' to 'kh point color" node.
2: will add a few options to 'kH Curls Advanced' to enable it to start directly from hair root.
3: there is 'kh Follow CurveList' node in latest download, geometry input is curve with many sub-curves - this should save you from so many inputs, if you merge these curves, using some script or add on. However it seems it didn't worked in some mixes of situations and SI versions. Will try to make this node as much 'ordinary' under the hood - there is a chance it will work, in any situation.

Thanks for showing my otto|rig work Izze :) i've been on the fence for a while now whether or not to share it.

@FXDude:

I'm really glad you liked what you saw of otto|rig :ymblushing: I made those videos back in March of 2012 and otto|rig has evolved quite a bit since then (I really need to get new videos out there). I would have loved to see how the community would have run with this. Unfortunately, at this time, there are not any plans to make it public (the tool is jointly owned and so not entirely mine to open source or monetize.)

We have been using, refining and adding to the otto|rig system since its inital completion in 2011. Gears, piston/shocks, suspension, wings, 3 & 4 joint IK/FK systems, squash & stretch FX rigs, etc. were all originally planned to be added until we got the gut-wrenching news about Softimage's untimely retirement. For instance, this one (based on the work that I did making rigs for the feature film "Werner - Eiskalt! (2011)") was almost "otto|mated":
