Live Render Coarseness

To enable In order to provide a quick feedback and allow interactive manipulationmanipulations, live renders always start with a very coarse image and refines its quality in a few iterations, each iteration taking more time. This The Live Render Coarseness option simply enable enables you to select the lowest quality (coarseness) the live renders starts with. More coarseness (larger pixels) provides faster frame rate during interactive manipulation at the expense of quality. The available options are 8, ?, ?, ? pixels. The default is 8 pixels, favouring interactive responsiveness (particularly when moving the during camera manipulation).


An image is rendered gradually in small groups of pixels called buckets. This option allows you to specify in what order the buckets are rendered. This option applies to both normal and live renders. It does not apply during batch rendering (i.e. when using Maya Batch). The default scanning is ????????. The available options are:


This options applies during normal renders only. It does not apply to Live Render (IPR), which is a separate rendering technique that is progressive by in nature (and allows allowing interactive manipulation). For normal renders, when this toggle is turned on, the rendering rapidly shows an image which is quite noisy 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 Render Settings) are ignored. A Box filter with a width of 1 is used instead. Also images rendering with this option may contain more noise / fireflies. Because of this, these images may differ slightly from your final renders using Maya Batch (remember that when using Maya Batch, progressive is ignored). Make sure to deactivate Progressive Render when rendering final frames.

Viewing Apps

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 BufferWhen this last option is selected, the render view used for rendering is specified through the 




config file


3Delight Display is used by default.

titleShow details about "Custom Frame Buffer" configuration???? This need to be revised....


The following statement in the rendermn3deliht.ini file config file controls which render view is used when Render View is set to Custom Frame Buffer:

Code Block
# default framebuffer is the i-display application.
/displaytype/framebuffer idisplay


The second section of this tab contains the names of the applications that will be launched to visualize the different assets entered data set/file specified in various 3Delight for Maya fields. The supported type of applications are listed in the table below.
