Width, Height, and Pixel Aspect
In order for the Locator to generate a correct 2D transformation, it must know the dimensions
and aspect of the image. These controls should be set to the same dimensions as the image
produced by a renderer associated with the camera specified above. Right-clicking on these
controls displays a contextual menu containing the frame formats configured in the
composition’s preferences.
Common Controls
Transform and Settings tabs
The remaining Transform and Settings tabs are common to many 3D nodes. Their descriptions
can be found in “The Common Controls” section at the end of this chapter.
Merge 3D [3MG]
The Merge3D node
Merge 3D Introduction
The Merge 3D node is the primary node in Fusion that you use to combine separate
3D elements into the same 3D environment.
For example, in a scene created with an image plane, a camera, and a light, the camera would
not be able to see the image plane and the light would not affect the image plane until all three
objects are introduced into the same environment using the Merge 3D node.
The Merge provides the standard transformation controls found on most nodes in Fusion’s 3D
suite. Unlike those nodes, changes made to the translation, rotation, or scale of the Merge
affect all the objects connected to the Merge. This behavior forms the basis for all parenting in
Fusion’s 3D environment.
Inputs
The Merge node displays only two inputs initially, but as each input is connected a new input
appears on the node, assuring there is always one free to add a new element into the scene.
–
SceneInput[#]: These multicolored inputs are used to connect image planes,
3D cameras, lights, entire 3D scenes, as well as other Merge 3D nodes. There
is no limit to the number of inputs this node can accept. The node dynamically
adds more inputs as needed, ensuring that there is always at least one input
available for connection.
