Your scene file determines
whether you render a single frame or an animation. You can render
from a shell or a command line. Before rendering, you may want to
close all applications, including Maya, to maximize the amount of
memory available for rendering.
When you render from
a command line, you can set flags that override some of the Render
Settings, saving time during test renders.
For more information,
see
Render from the command line.
To get quick renderer-specific information
- Type:
Render
-r rendername -help
where rendername is the
name of the renderer.
Use the following options:
- mr =
mental ray
- sw =
software renderer
- hw =
hardware renderer
- vr =
vector renderer
- file = the file within which the renderer
is specified
NoteIf you get help on
a file (-r file -help), only the flags common to all renderers,
not a specific renderer, are shown. If you want renderer-specific
information, you must specify the renderer.
All flags have a short
description. Each flag corresponds to the appropriate section of
the Render Settings window. See
the Render Settings documentation
for more detailed information on each option.
To obtain a complete list of command
line Render options, from a shell or command line
- Type:
Render
-help
To render a scene with a specific renderer
from a shell or command line
- Type:
Render
-r <renderername> <options> scene
TipYou may need to provide
the
-proj flag when
issuing the render command to specify where the scene file is located.
For example, type:
Render
<options> <projName> scene -proj
To render a scene with the renderer specified
in the file from a shell or command line
- Whichever renderer is specified in the
file is used to render the scene.
Type:
Render
-r file
To batch render using user-defined region rendering
- Use the -reg flag.
For example:
render
-r mr -reg 0 100 0 100 scene.ma
where -reg 0 100 0 100 indicates the region
to be rendered in pixels (left, right, bottom, top).
The above command renders
the lower left 100 x100 pixel region of the scene.
