Node Description and Purpose
The Render node is one of the main nodes in Terragen 2. The Render node contains the settings used to produce final renders and is also used to start rendering animation sequences. The Render node works in concert with the Camera node to create a render of your scene from a specific perspective.
Basic controls include the Width and Height of your output image, the camera from which your scene will be rendered, overall scene Detail, and Antialiasing. Many additional controls for fine-tuning scene detail and quality are also provided, including Global Illumination (GI) settings, as well as Contrast and Gamma Correction functions. You can also render partial crops of your select cameras view using the Crop Region functions. Sequence/Output allows you to output a sequence of images for animation (only functional in Animation version).
When you start a new project in TG2 there are two render nodes created for you. One is called "Full Render" and the other is called "Quick Render". Both of these nodes are Render nodes. The difference between them is that "Full Render" has preset settings more suitable to a final render whereas "Quick Render" has lower quality presets suitable for a quick preview render.
Master: Check this to make the node the Master render node. The Master render node is the one which will be used to render projects loaded from the command line or a batch file.
Image width: This param sets the width of the rendered image.
Image height: This param sets the height of the rendered image.
Lock aspect ratio: If this is checked then the image aspect ratio is locked. When you make changes to the image width or height the other param will be changed so that the aspect ratio of the image is maintained.
Aspect ratio: You can change the aspect ratio for the image using the controls under the Lock aspect ratio param. Values greater than 1 will make the image wider and values less than 1 will make the image taller.
Camera: This param sets the Camera node used for rendering the image. A Render node must have a camera assigned to it before it can render.
Surfaces visible: If this is unchecked surfaces are not rendered.
Atmosphere visible: If this is unchecked the atmosphere is not rendered. This might be useful if you are rendering orthographic images for texture overlays in another application, for example.
Do shadows: Uncheck this to stop shadows rendering.
Render Image: Clicking this button will start the render.
