IGA - Produit Gratuit

Hey there,

here we are again with a new IGA spot and some behind the scene material!

As usual, here are our work in progress on the animation side. We start with the 2d storyboard drawn by our artist Benoit Therriault:

Transfered into 3d for the 3d Animatic where we set the timing and make sure the drawing translate well into 3d.

Then the animators get to it and make some awesome animation. This is a work in progress of it toward the end of the production.

And the final animation in all its glory.

Obviously, for this ad we had 2 main characters we had to develop. We started from drawing, and then went through several passes of refinement to make sure the clients/agency liked them. For example, the lady had to seems really kind, not too old, and above all interested in what the IGA employee was offering. As for the guy, a lot of effort was given to give him the proper "red" color for his hair, because it was part of the "clash" between his look and the Santa Claus suit.

Finishing the look of the Hair on the Santa Claus Suit
Here's a small screen capture of a layout rendering:

 We try as much as possible to rendering everything in single passes to take advantage of all the arnold GI bounce. It leads to rather long rendertime, but we always manage to squeeze it in our timetable.

The hardest part of this spot was obviously the management of all the hair on the Santa Claus suit while that suit was cloth simulated using Syflex.  We started doing "technical" render pass to make sure our hair rendered fine.  With very low sampling and no "heavy" shader, we could render very fast frame and make sure the hair didn't pop, or went through mesh, or that our displacement was alright, etc. Here's an exemple of an "hair check" pass:

Another tricky thing in this production was the "magical" transformation of Santa Claus. It's always hard to describe the word "magic" with words, since everyone has a different interpretation of it.  So we had to go through several test and finally present this to the client. We also use these render to complement our "hair check" and make sure our Geo and hair is still solid further down the pipeline.

And with the compositing to complement the effect:

And for those interested, here's some screen capture of the Compositing step:

 And here's a color chart which we use to make sure we stay withing the palette of color throughout all our IGA commercials.

Hope you enjoyed this little Behind the Scene! :)
