uMerge Node

The uMerge 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 uMerge node.

The uMerge provides the standard transformation controls found on most nodes in Fusion’s USD
suite. Unlike those nodes, changes made to the translation, rotation, or scale of the uMerge affect all
the objects connected to the uMerge. This behavior forms the basis for all parenting in Fusion’s 3D
environment.

uMerge Node Inputs

The uMerge node displays three 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.

These inputs are used to connect USD image planes, 3D cameras, lights, entire USD scenes, as well as other uMerge 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.

The Transform and Settings tab in the Inspector is also duplicated in other USD nodes.
