Cinema - Render Region Tag

The Render Region tag is placed on a Cinema camera, or a Scene Object, and used to define a visible rectangle to use with Maxwell's Render Region and Render Blow-up features. As it is implemented as a persistent tag, rather than a dynamically-selected 'rubber-band' region, the Render Region tag offers the ability to consistently render the same region multiple times if necessary, or to divide up a large rendering into smaller portions without needing to know the actual pixel dimensions involved.

Options

The parameters in this section are used to enable or disable this Render Region (it will be ignored when disabled, or when its camera is not active), to change the colors used to paint it on the screen, and whether it will be used to perform Maxwell's Render Region or Render Blow-up function. Render Region simply excludes all pixels outside of the specified rectangle from the rendering (i.e. they will just be rendered black), resulting in a faster render of the desired pixels. Render Blow-up uses the specified rectangle to zoom in on the viewport, and renders the selected rectangle at the full height or width of the output resolution.

Rectangle

The Left and Top parameters define how far from the left and top edges of the rendered area the rendering rectangle begins. The Width and Height parameters define the size of the rectangle, as a percentage of the rendered area's height/width.
