Andy Moorer is a VFX artist and TD working in the film industry.

Since LK Fabric is out I dug up one of the early test scenes we used on Nike “Evolution” at Royale in which we developed some of the techniques we used to get various looks. This setup is very basic but covers some of the key tricks for getting a natural result and was used as a starting point for a number of shots.

I have replaced the original many-versions-old compounds with ones from Leonard’s public release, and have also left in a few “helper” compounds I built which weren’t part of his official release. I then removed everything superfulous to the basic effect and commented the resulting ICE tree throughout. Any typos or misspellings are entirely my fault. :D

The actual setup is very simple.

This scene demonstrates:

  • A basic setup of a single evolving swatch of fabric, with the most basic pattern and the modifiers we used most often.
  • Using the “slide profile over U/V” compound and other techniques to shape the leading edge of fabric growth.
  • Using the “offset” core parameter to make the leading strands animate and form a shape for the thread tips.
  • Using a second ICE “post” effect to add per-strand variance and “frizz” effects.

The early tests like this were pretty chaotic, we knew the system did a good job of creating a “perfect” weave so we were pushing in the other direction and adding ways to create chaos and randomness.

Ironically despite the first briefs being focused on “organic” and “evolving” concepts the client spent much of the latter half of the job dialing in a more out-of-box mechanical look… that’s the way it goes sometimes. But this means there is a lot of capability which hasn’t been seen yet. I’d love to see some people use some of the per-strand and per-thread modifiers, and the capability to create patterns beyond the basic “canvas,” to create a more organic, aggressive look.

Here’s a scene file and a couple of compounds which compute a simple noise function and then create a reticulated “push” from it. It’s meant to demonstrate how a simple spatial noise can be layered on itself to create a fractal, visually pleasing result, as well as give a little insight into how functions like perlin, worley, turbulence etc can be similarly layered to create a huge variety of natural looking patterns.

LK Fabric released

By · Comments (0)

LK Fabric has been released!

Congrats to Leonard Kotch who put his heart and soul into this and who put up with my endless demands for the system during the production.

Pretty much everything you see in the Nike commercials below was built with this system, with Leonard doing daily updates as we worked. We barely touched some of the possibilities of this system, I hope people will try it out because it is cable of some truly spectacular effects. Kudos to Royale for being so cool and sharing it out like this!

Most people who have worked with me know that my former career was quite different: I was a Paramedic for quite some time. A fun and challenging job, I salute those in EMS who put themselves on the line every day to be there when we most need it.

I also like to write, and still occasionally write or share opinions or the occasional gruesome story when the mood strikes me. One became an article which was printed today by The Huffington Post.

Softimage, Arnold, ICE and LKfabric, intensive small-team project @ Studio Royale, I think this video is meant to play in the Nike stores inside of a sculpture/model of the loom. If anyone sees it in one of the store sculptures, send me a pic, it sounds cool. :)

Ideas, traveling

By · Comments (0)

Pingo van der Brinkloev hit me up for a very rough discussion of the conceptual approach to building knitted patterns in CG and came up with a pretty cool workflow to get similar results in C4D. Cool, nice work!

Art is collaborative. It loops back and forth between artists, techniques grow and we present constant challenges to ourselves and each other. Nothing makes me happier than to see this kind of mutual exchange of ideas across different toolsets. We are artists first, inspiring one another – the borders of studios, tools, location, language or genre should never keep us from exchange of ideas. Thriving ideas lead to a thriving market as a whole, employed artists, and most importantly better art across the board. I really believe lifting each other up is the best route to success for the individual artist as well as the industry as a whole, so when I saw how Pingo built this I was as excited as I was when I saw Jonah Friedman make entwiner in ICE. How can you not get excited? This is cool stuff!

Two of 3 spots. “Evolution” was a small team, 3 weeks, lighting and effects with Softimage and Arnold.

I love small but intense projects like this.

“Run” was primarily Maya/Vray with a touch of ICE. The studio (Royale) is only 6 years old but advancing fast, and it’s been a real pleasure working with them. For their first exploration of ICE, Royale invited in some familiar SI friends – Ciaran Moloney, Steven Caron, Leonard Kotch, Billy Morrison and yours truly doing a first gig start to finish as a CG sup (which with guys like this mostly involved saying “go for it.”)

Like the Psyop “Telstra” spot, this commercial essentially required us to create a system for knitting cloth from massive numbers of strands. Leonard Kotch wrote a system which performs many of the same tasks as the Psyop “Entwiner” tool, but he took a slightly different direction, it was fascinating to compare how the two diverged. The progressive animation required for these two shots resulted in a pretty flexible and broad system, which we are currently using for the last of the three spots, which will wrap in production soon.

Royale has been an enthusiastic and fun group to work with and it’s been great getting to show a studio as strong as they are in design some of the possibilities ICE can bring to jobs like this. Expect to see some version of Leonard’s “LKFabric” system gifted to the community before long – very cool Royale, thanks! (They also throw good parties, their 6′th birthday celebration was impressive and… unusual.)

Strands are our friends

And so is Psyop!

This little commercial project from a while back was a LOT of fun. A very small team of us (5 or 6 total, I think) made this (plus a few shots more) in just a few short weeks (two or three I forget) at the LA studio, using a hybrid Maya/Softimage approach which Psyop does really well. All models and animation in maya are brought to Softimage for lighting with Arnold and additional ICE effects – in this case, the characters, and stuffing are entirely strands. No geometry aside from the little plastic eyes and their teeth.

Psyop’s lighting supervisor Jonah Friedman wowed me with the system for knitting via strands he built, and how fast he built it. He also quickly made it on my “favorite people” list in general, it was a blast working with him and the others there. The system, which we called “entwiner” builds layers upon layers of strands… these knit characters are built down to every individual fiber. And Arnold powered right through these millions of strands without a blip. Pretty cool. It was so efficient at it in fact, that it made sense to make the “stuffing” out of tiny fibers too, which gave it a nice volumetric kind of feel when lit.

The liquid is a simple lagoa setup, with wet maps generated in ICE. While the commercial was so simple I was really pleased with how the studio took pains to take their clients ideas and give it the very best. A couple of knit characters could have been faked with geometry and textures, but going that extra mile even when time was so short is what really impressed me, and the combination of maya/softimage, ICE and Arnold is a powerful one, as Psyop shows even on small jobs like this. My kind of studio. Thanks for having me you guys.

Since at the moment I am heads-down in production and can’t share the art I’m working on, I thought I would take a second to share someone else’s art – in this case a favorite piece by the wonderful and whimsical dance troupe, Momix.

While I have been lucky enough to have seen Pilobolus, The Alvin Ailey Dance Company, Martha Graham, and even some rare offshoots like Iso and The Bobs, I have never seen Momix live. If you like good art and have an opportunity to do so yourself, don’t pass it up.

And while I’m mentioning performance artists of the kinesthetic sort, if you live on theWest Coast and haven’t spent an evening with the
Flying Karamozov Brothers, good lord – what’s keeping you?
