MAKING OF WITH SCRAT

Transcript

00:00On Ice Age, effects pretty much cover everything that you see moving that is not a main character.

00:18In traditional special effects, you're trying to create something that looks real.

00:22In Ice Age, we're dealing with a cartoon world.

00:25The idea that gravity only takes effect a few seconds after you fall off the cliff.

00:29A cloud of dust doesn't just woof out, it goes woof.

00:32And because of that, the process that we went through to develop the effects was to take a basic physical model

00:37and have it emote the feeling of the shot rather than just what it would really look like in real life.

00:42In order to get this effect of this huge glacier crashing down on this poor little scrat,

00:47we took a whole bunch of different little elements, combined them together into one big scary mush.

00:52We had to take the bow wave of the glacier moving through the snow, we took the dust,

00:57we took the chunks of rock falling all around.

00:59In order to do that, we do it in a series of layers, a series of passes, that allows us to isolate each element

01:05and deal with it on its own so that we're not dealing with the weight of the entire system.

01:09What was interesting about Ice Age was that we had so many different kinds of creatures to rig,

01:14that moved in so many different kinds of ways.

01:16Each character was a rigging challenge.

01:18Rigging is like creating a marionette or a stop-motion armature.

01:22Anything an animator might want to move, rigging has to prepare for that.

01:26It has to create some sort of control, some sort of handle that you can grab and then cause the leg to twist,

01:32an arm to bend, the face to move.

01:34We take the final geometry from the modelers, we create a skeleton within Maya,

01:39and we use this skeleton to deform the character.

01:43There are hundreds, perhaps even over a thousand, perhaps different things that an animator could possibly animate in the character rig.

01:50What we did to deform the characters was bind the geometry to the skeleton that we created.

01:56Geometry, of course, is made up of a series of points.

01:58We could bind the points of the lower arm to the lower arm skeleton,

02:02so when the lower arm skeleton rotates, those points are going to move with the skeleton.

02:06What we experimented with were adding in cartoonish controls.

02:09For instance, when the Scrat is yanking at the acorn, his arms are actually scaling,

02:14they're increasing in length, the bones are actually scaling out.

02:17We would add special sort of deformation controls and make the eyeballs scalable,

02:22just to sort of emphasize the drama of the action or the pose.

02:26All the things that we do are you're doing is that you are guiding the puzzle.

02:28They essentially станете the same with your shape to be prepared for your child.

02:30They could never do so.

02:32Aaaaaaaaaaaaaaah!

02:34Aaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaa!

02:36Aaaaaahhh!
