File Name Prefix: each frame of you animation is a separate image file. Fill in a name here which will be the first part of the name of each frame. Frame/animation ext: name.#.ext Please use exactly this format for your renders - it means the first part of each frame image is name, then the frame number, then the format type extension. Start/EndFrame: start at frame 1 and end at frame 300 By Frame: 1 here means you will render every frame Frame Padding: set to 4 digits (this will give you a file name like: name.0001.tif) PLEASE AVOID USING 3 DIGITS. Use only 1 or 4 Image Format: use Targa or Tif Channels: The RGB channel is the color channel, you must render this to see your scene, the Alpha channel will create a mask around your geometry which allows you to composite the animation later, if you want.
Now let's go back and add some features. The nostrils are indented on the surface of the muzzle. We need to cut a couple of nose holes in the muzzle and fill it in with a concave surface. One easy way to do this is by intesecting a small sphere with the muzzle and trimming away part of the muzzle and part of the sphere. Create a small Nurbs sphere and place it so that it intersects the muzzle where you want a nostril. Make a mirror duplicate of this sphere now for the other nostril
