Actually, we call all the other sheep 'average' sheep in the studio - although they come in many shapes and sizes, as the scene I have been working on in the last week shows.
I have been working on en episode about a crow who is keeping the flock awake at night. In this scene, I have been animating Shaun trying to quieten the crow, while trying not to awaken the other sheep. In these stills you can see Shaun addressing the crow, and other sheep are about to angrily throw their pillows at him for making so much noise! Poor Shaun - he's only trying to do a good deed.
Each cushion had to have its own rig, which was a piece of ally-wire attached to a strong magnet. These of course will be painted out later, but when they were being thrown I had to try not to let the rigs overlap any action. If they do, I have to take the cushion and wire out and take another 'empty' frame, or 'checker-board', as we call it. This ensures there will be enough information to be used for painting out the rigs later in post. The second photo shows the set as a whole, complete with the camera.
The final three photos show a different shot, where I had to make Bitzer wave a scarecrow around to try and scare the crow away. The director asked me to make it look very scary - not just for the crow, but for the audience. Yes - that means you guys. Whooooo! If you look carefully at the first photo of the scarecrow you will see the rig that he is perched on. This includes a 'winder' that allowed me to move him back and forth. Bitzer was made to look like he was holding it all by himself, when in fact he wasn't - basically because it would have been too heavy for the puppet, and I would have had less control with the animation. The last photo shows the shot as it will appear in the final episode, with the rig completely out of shot. The scarecrow himself was fully armatured, and I was able to move his body around, and 'off set' the arms, which basically meaned I could delay them to the body movements, meaning they could move left while the body was moving right, and vice versa.
I'll be happy to answer any any questions - and I'll have more to share on here this weekend.
