Nike Inneva

Hi Everyone

After two and a half weeks we have just finished a video for the new Nike Inneva shoe.
The agency we worked for was Accept and Proceed.
Hope you guys like it and if you have any questions it would be great to hear them

Wow! Are you free to talk about how it was done? Very nice.

HI Rochre26

Sure we can chat about it,what would you like to know?

techniques

How did you make the fibers and how did you get them to interlace to form the shoe? The way they interweave is so intricate. Also, the texture on the laces is so detailed I want to say its displacement but I'm not entirely sure how you did it. What sofware and renderer did you use? Feel free to add any problems you anecountered and how you solved them. I'm a bit stumped on how I would even approach this.

Great questions Rochre26

First off here are the programmes used on this project:

Aftereffects CS5.5
Cinema4d R13
Adobe Premiere CS5.5
Photoshop
Modo
Zbrush


"How did you make the fibers?"
The fibers where very challenging as we had a very tight deadline and due to the handwoven nature of the shoe we couldn't create a smart script that would tackle the issue.

The only solution we could think of that would give us the control was to use 94 splines that were hand weaved manually using points.After that we create strips of weave and deformed them along the splines to create the desired effect.Each weave had its end modeled to create a thread like look.We then used a animated morph on each tip to give us a bit of dynamism.

"was the lace texture displacement?"
We created a procedural bump map for the laces and created a variable spec map.We then animated the UV of the material to give the illusion that the laces where moving.We wanted to use Micro poly displacment but in the end we didn't need it.

Challenges :

There were many challenges on this project,The main challenge was time.Two weeks among a small team isn't much.Early on we decided to 3d scan the shoe due to it being handwoven and pretty tough to get right.Thanks to James at ten24
For doing a great job of the scan and clean up.

The only issue was we needed to carry on with the rest of the project while the shoe was being scanned.Our biggest Challenge was the showing the shoe tighten up whereby the individual weaves pulled underneath each other.

Tightening the Weave :

This was by far the trickiest effect to achieve.We had three closeups and a side shot of the weave tightening.We had to create bespoke weaves for the loops of the laces for the closeup shot.the laces where first put into place using a spline and then bones where used to create the loop.The reason for this was that we wanted our UV to be perfect and we need to leave the option of the loop straightening out if need be.

With a mixture of Blend morphs to move the loop and animating the UV texture we where able to give the illusion that the threads were moving under each other.

There is a particular shot in the piece where we are side on on the shoe and the weaves all tighten together. This was a last minute shot that the client wanted , after a head scratch we were able to use the 3d scanned shoes own uv to animate the Threads on the texture map . This resulted in a 7 k texture map that ran for the duration of the shot.C4d handled it and everyone was really happy with the result.

Woven Landscape:

We used C4d wind deformer on a spline which after various tweaks we got to weave.Thanks to C4d render instance function we did that pretty quickly and render times where fast.
The first test we did had AO on them but in the end we found using soft area lights was faster and due to the dark nature of the video AO wasn't lending anything to the process.

The Dot Foot:

although this effect looks easy it was in the end a bit hard to nail down.The client was very specific of what they wanted and we managed to match that using a Proximal shader and a cloner that spread out little glow spheres along vertices of a modeled foot.We used objects attached to the shader to define what areas lit up and which areas disappeared.

The Unfolding Threads in the intro sequence:

Here we used one animated spline that we cloned a few times and using the step effector we were able to offset the animation easily.We then used the splines to deform individual pieces of mesh.We also used displacement to create a more bumpy look on the threads.

Thanks and congratulations

You and your team certainly rocked it.

The shot of the shoe tightening really stood out to me even before I knew it was so involved.

Thanks for the explanation.
