The 3Delight Preferences dialog contains settings that remains effective across all Maya scenes.
Render Engines
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
Live renders always start with a a very coarse image to enable a quick feedback. It then refines its quality in a in a few iterations (3 to 4), each iteration taking more time. This option simply enable you to select the lowest quality (coarseness) of the live renders. More coarseness (larger pixels) provides faster frame rate during line manipulation at the expense of quality.
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. The default scanning is ____________. The available options are:
| Option | Description |
|---|---|
| Horizontal | The buckets are rendered row by row, from left to right and from top to bottom. |
| Vertical | The buckets are rendered column by column, from top to bottom, and from left to right. |
| Zigzag | The buckets are rendered row by row, from left to right on even rows, and from right to left on odd rows. |
| Spiral | The buckets are rendered in a clockwise spiral starting at the centre of the image. |
| Circle | The buckets are rendered in concentric circles starting at the centre of the image. |
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 Buffer. When this last option is selected, the render view used for rendering is specified through the rendermn.ini file; 3Delight Display is used by default.
