TERMINATOR SALVATION: interview of Natasha Devaud !!!

This new Terminator movie has a huge level of effects, 1300 shots !! ILM did almost 400 of them among the most complex.
The others shots are divided between Asylum (face remplacement), Rising Sun Pictures (submarine sequences and some Hunter Killer explosions).
Imaginary Forces did the titles design and the terminator's POV. Matte World Digital was in charge for the matte-paintings. Kerner Optical (who was before the ILM model shop) and New Deal Studios did the models.
The pre-viz was done by two studios, Proof and Pixel Liberation Front.
The special effects makeups were done by Legacy Effects (that was Stan Winston Studio but renamed that way for a tribute to the master).


The visual effects supervisor for the movie was Charles Gibson (Pirates of the Caribbean trilogy) and for ILM it was Ben Snow who is very familiar with CG robots. He supervised IRON MAN and he's now supervising IRON MAN 2 !!

Natasha Devaud, senior TD, answer some of my questions about his work on the movie:

Hi Natasha. Can you tell us on which sequences you have worked ??
I worked on the sequences with the hydrobots (these snake-like robots underwater) and inside the factory. I also did the look developpment of the hydrobots and several digital doubles from live actors.

In what consist your job ??
As a TD (technical director), I gather the work of the layout people, the animator and creature dev people (sim of cables, skin, ...), and add all the textures and lighting to the characters, which I then render to hand out to the compositor. 
The work of the TD is bit like the center point of a shot, with most of my time being spent creating realistic lighting to make the CG effects blend seamlessly into the background.

After TRANSFORMERS and IRON MAN, ILM is the reference for CG robots.  What was the challenge this time ??
One of the big challenge was the CG Arnold. Very tricky. And also the nature of some of the shots where the lighting on the background plate would be different at every frame. Given the metallic and reflective nature of the robots, these constant changes had to be applied on them as well.

To which step did you use the puppets of Legacy Effects ??
We used them as references to develop the textures, materials and look in general, and the way they react to the light.

For the animation of the robots, have you used IMocap (motion capture device developped by ILM on Pirates of the Caribbean 2) ??
No, it's all hand animated.

The render of the robots are impressive. How did you get this result ??
We used a new technic of lighting, image-based.

Did you have encounter some problems ??
Arnold was quite difficult, and as mentionned earlier, the fact that the environment was constantly changing on some of the sequences.
On the animation side, the biggest challenge was to make these robots look as realistic as possible in their movements while giving them a sense of heavyness due to their size. Some of the interractions between the cg effects and the live-action background was also quite challenging. Think about shots where we had to add heavy damage to real structures.

What was the most complicated sequence to achieve ??
Probably Arnold. But pretty much every shot has its challenge.

How was the collaboration with Charles Gibson and McG ??
I didn't interract directly with them, but I think, it went very well. The crew on the ILM side was excellent, led by Ben Snow who's a great visual effect supervisor.

What's your next project ??
Can't say yet as I'm not sure myself. I just finished Transformers 2 and will take a few weeks off.

Thanks a lot for your time and help. Congratulations for your great  work !

An another interview about this movie will be soon online !!
Raffael Dickreuter of Pixel Liberation Front give me some of his time for my questions !!
