The Render Engine Tab
This options applies during normal renders only. It does not apply to Live Render (IPR); a separate rendering technique which is progressive in nature and allows interactive manipulations. For normal renders, when this toggle is turned on, the rendering rapidly starts with a noisy image and refines it progressively until completed. Progressive Render has a slight overhead and may increase render time in the order of 5-10%.
When using Progressive Render, the Filter Type and Filter Width attributes (specified in the Quality group of the Render Settings) are ignored in the coarse passes. A Box filter with a width of 1 is used instead. Also, images rendering with this option may contain more noise / fireflies. Because of possible optimisations, images produced using progressive renders may differ slightly from final renders using Maya Batch (remember that when using Maya Batch, progressive is ignored). Make sure to deactivate Progressive Render when rendering final frames.
The Viewing Apps Tab
The first section of this tab contains the Render View option for selecting the window (and application) in which image layers will be displayed on screen during rendering. See Image Layers (AOVs). It can be either the Maya Render View, 3Delight Display or Custom Frame Buffer. When the latter is selected, the render view used for rendering is specified through the
3deliht.config file. 3Delight Display is used by default.
The following statement in the
3deliht.config file controls which render view is used when Render View is set to Custom Frame Buffer:
# default framebuffer is the i-display application. /displaytype/framebuffer idisplay
The second section of this tab specifies the location of the applications that will be launched to visualize the different types of data sets/files specified in various 3Delight for Maya fields. The supported types of applications are listed in the table below.
|NSI||This application will be launched to view NSI files. The default application is WordPad on Windows and TextEdit on Mac OSX. There is no default application on Linux.|
This application will be launched to view rendering log files. The default application is WordPad on Windows and Console on Mac OSX. There is no default application on Linux.
|Image||This application will be launched to view images. The default application is 3Delight Display (a.k.a i-display) on all platforms.|
This application will be launched to view statistics output by the rendering process. The default application is Internet Explorer on Windows, Safari on Mac OSX and Firefox on Linux.
