Render Type

Main toolbar > Render Type

Render Type lets you render only a portion of the scene.

The Render Type list lets you specify the portion of the scene that will be rendered.

Two new render types have been added in version 4 of the software: Region Selected and Crop Selected. They are described below.

Procedures

To render selected objects:

Choose Selected from the list.
Make the viewport active.
Select the objects.
Click a render button.

To render a region:

Make the viewport active.
Choose Region from the list.
Click Render Scene or Quick Render.
A window is displayed in the active viewport, and an OK button appears in the viewport's lower-right corner.
Drag in the middle of the window to move it. Drag the window's handles to adjust its size.
To preserve the window's aspect ratio, you can hold down CTRL while you drag a handle.
Click OK.

To render a blowup:

Make the viewport active.
Choose Blowup from the list.
Click Render Scene or Quick Render.
A window is displayed in the active viewport and an OK button is displayed in the viewport's lower-right corner.
Drag in the middle of the window to move it. Drag the window's handles to adjust its size.
The window is constrained to the aspect ratio of the current output size.
Click OK.
The software displays a progress dialog that shows the progress of rendering and the rendering parameter settings. To stop rendering, click Cancel in this dialog, or press ESC.

Interface

View—Renders the active viewport (default).

Selected—Renders the currently selected object or objects only.

Region—Renders a region within the active viewport. Use this option when you need to test render a part of the scene.

Note: Region rendering is used as a draft rendering of a selected area for further refinement of a scene. As such, Region rendering only uses an Area filter for antialiasing despite selection of a different filter in the Render Scene dialog.

Crop—Lets you specify the size of the output image using the same region box that appears for the Region and Blowup categories

Blowup—Renders a region within the active viewport and enlarges it to fill the output display.

A rectangular selection region appears when you render with either Blowup or Region selected in the Render Type list. You can change the size of the region by dragging its handles.

Box Selected—Calculates the aspect ratio of the current selection’s bounding box, and then lets you specify a width and height for the rendering, while providing the option of maintaining the aspect ratio.

Region Selected—When an object or objects are selected, renders those objects and other objects within the selection's bounding boxes, but does not change the rendering outside the bounding boxes.

Objects within the bounding boxes, including objects in front of or behind the selection, are rendered.

When no objects are selected, Region Selected renders the entire frame.

Crop Selected—When an object or objects are selected, renders those objects and other objects within the selection's bounding boxes. The rendering is cropped around the region defined by the bounding boxes.

Objects within the bounding boxes, including objects in front of or behind the selection, are rendered.

When no objects are selected, Crop Selected renders the entire frame.
