Maya
software only.
When you drag a marquee
(render region) around the entire scene or part of the scene, the
IPR image begins to update. If you change lights, shadows, materials,
textures, and post processes (special effects) such as glow and
fog, you can see the results of your changes interactively.
For detailed information
on IPR rendering, see
Interactive Photorealistic Rendering (IPR).
NoteThe amount of memory
used during an IPR session may be considerable. The upper-right
corner of Render View displays how much
memory is being used for the current IPR tuning region.
To visualize scene adjustments interactively
- Do one of the following:
- Click the scene view you want to render,
then click the IPR Render button (from the Status
Line or from within Render View if
it is open). The scene appears in Render View,
and an IPR image is created.
- To load an existing IPR file, select File
> Open IPR File..., then select the file.
- Marquee
select a region within the IPR rendered image in Render
View.
NoteYou must select a
region to adjust before you start to modify rendering attributes.
The region you select determines the amount of memory required by
IPR to re-render the adjusted region.
- Adjust the scene, for example, add lights
or modify materials and texture attributes.
The selected region of
the IPR image updates as you adjust the scene.
- To render another view instead, select IPR
> IPR Render in Render View and
select a view from the drop-down list.
- If you change the view (such as tumble
or zoom, or add new elements to the scene) and want to update the
result, click the Redo Previous IPR Render icon
in Render View or from the Render menu
in Maya’s main menu bar.
- If you only want to change certain elements
such as lighting or textures and do not change the view, simply
drag a marquee around the object or part of the object you want
to update. The results in Render View are immediate.
TipAfter you marquee
select a region, you can drag materials and textures onto objects
within the region, just as you can make connections by dragging swatches
from Hypershade onto surfaces in
the views.
Pause, cancel or save an
IPR render
To
pause an IPR render
- Press the pause button.
To cancel an IPR render
- Press Esc.
The IPR render stops.
You cannot adjust a cancelled IPR Render;
you must perform a complete IPR Render to
adjust a region.
To save an IPR file
- Select File > Save IPR File....
The Save IPR File window displays.
Type the name of the file and click Save.
NoteBecause an IPR file
saves the deep raster information in addition to the visible color
information, an IPR file can be very large. Ensure you have sufficient
disk space.
Batch render IPR files
You
can batch render IPR files from the command line.
For more information
about batch rendering or command line rendering, see
Batch renders from within Maya (UI) and
Render from a command line.
To batch render IPR files
- In a shell or command line, type:
Render
-r sw -ipr true <scene>
See
Render from the command line for
information and flags about batch rendering from the command line.
Note
- You cannot batch render IPR files from
within Maya.
- Batch rendering to produce IPR files
is not multi-threaded.
