З.Ы. Обрати внимание на Image Format. Это оно. Мувик!!!!!!!!!
Maya Rendering Render Globals
Image File Output
Controls the file name and extension of rendered image files.
File Name
Displays a preview of the file name for rendered images.
File Name Prefix
The base name for all rendered image files in an animation.
Note
When choosing basic file names for an animation, avoid using periods; use underscores instead. For example, use:
xxx_yyy.iff.1
instead of
xxx.yyy.iff.1
Frame/Animation Ext
The format (syntax) of rendered image file names. The following are available:
The name of rendered image files can consist of three separate components: file name, frame number extension, and file format extension. A combination of these three components is referred to as the file name syntax.
Start Frame, End Frame
Specifies the first (Start Frame) and last (End Frame) frames to render. Start Frame and End Frame are only available if Frame/Animation Ext is set to an option containing # (see also Setting file names and extensions). The default value for Start Frame is 1; the default value for End Frame is 10.
By Frame
The increment between the frames you want to render. By Frame is only available if Frame/Animation Ext is set to an option containing #. The default value is 1.
Frame Padding
The number of digits in frame number extensions. For example, if Frame/Animation Ext is set to name.ext, and Frame Padding is 3, Maya names rendered image files name.001, name.002, and so on. The default value is 1.
Image Format
The format for saving rendered image files. See also File formats for rendered images. The default setting is Maya IFF.
Renderable Objects
Controls whether Maya renders all objects (Render All) or only selected objects (Render Active). The default setting is Render All.
Camera
Controls which camera generates an image during rendering. The default setting is persp.
Channels
Controls whether rendered images contain color, mask, and/or depth channels. The default setting is RGB Channel (Color) on, Alpha Channel (Mask) on, and Depth Channel (Z Depth) off.
