Rendering a Region of Interest (ROI)

To reduce the render time while making changes, you can render a smaller section of the image - this section is called a region of interest (ROI). The region of interest is only used for interactive renders and is ignored when performing a Disk Render or Disk Render with Dependencies.

You can turn on region of interest rendering by selecting [ROI menu] > ROI On or ROI On (visible). If you then want to turn it off again, select [ROI menu] > ROI Off or ROI Off (visible). You can also toggle the state of the ROI by pressing Shift+RMB. This toggles between ROI Off and ROI On (visible). Alternatively, select an area for the region of interest by Shift+RMB and dragging the mouse to create a selection box.

Note:  If the region of interest’s bounding rectangle is visible, you can change the bounds by dragging the edges.

Tip:  Should you need to access the values of the ROI for scripting purposes, they are stored as parameters on the project root node.
