Progressive Render

When this toggle is turned on, the rendering rapidly shows a coarse image and refines it progressively until completed. Progressive Render has a slight overhead and may increase render time in the order of 5-10%. This option is effective only for images outputted directly to a window on screen (i.e. to the Maya Render View or to 3Delight Display). During batch rendering (i.e. when using Maya Batch) this option is ignored. This option is also ignored for Live Render (IPR), which is progressive by nature.

Warning

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, images rendered with this option may differ slightly from your final renders using Maya Batch. Make sure to deactivate progressive refinement when rendering final frames (as stated above, when using Maya Batch, progressive is always ignored).

Live Render Coarseness

...

offers options for a user to setup per his or her personal preference when using 3Delight. As such, these settings:

  1. Are independent of the Maya scenes/projects? the user is working on.
  2. Are effective across all Maya scenes/projects? the user is working on.
  3. Have no effect on the resulting image from the rendering process (i.e. they do not affect the project a user is working on).

All the preferences liste here, including the Render Engine preferences, are ignored during batch rendering (i.e. when using Maya Batch).

Live Render Coarseness

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

Scanning

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. Rendering will be more memory-efficient if a bucket order that minimizes the number of objects being rendered simultaneously is chosen. 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:

OptionDescription
HorizontalThe buckets are rendered row by row, from left to right and from top to bottom.
VerticalThe buckets are rendered column by column, from top to bottom, and from left to right.
ZigzagThe buckets are rendered row by row, from left to right on even rows, and from right to left on odd rows.
SpiralThe buckets are rendered in a clockwise spiral starting at the centre of the image.
CircleThe buckets are rendered in concentric circles starting at the centre of the image. 

Progressive Render

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 nature (and allows interactive manipulation). For normal renders, when this toggle is turned on, the rendering rapidly shows an image which is quite noisy and refines it progressively until completed. Progressive Render has a slight overhead and may increase render time in the order of 5-10%.

Warning

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 Output: 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 rendermn.ini file; 3Delight Display is used by default.
