The Merge3D Node
The Merge3D node combines the output of one or more 3D nodes into a single scene. Unlike
the Merge2D node, the ordering of elements in the scene is not restricted to only background
and foreground inputs. Instead, the Merge3D node lets you connect an unlimited number of
inputs, with the resulting output combined according to each object’s absolute position
in 3D space.

Combining Objects Directly
While the Merge3D node provides a structured way of combining objects, you can also
combine 3D objects such as Text3D and Shape3D nodes by connecting the output of one 3D
object node to the input of another, as seen in the following screenshot. When you do this, you
must use each node’s internal transform parameters to transform their position, size, and
rotation directly, but the transform control of downstream 3D object nodes also transforms all
upstream 3D object nodes. This even works for lights and the Camera3D node, giving you a
fast way of combining a set of objects that always go together, which you can later connect to a
Merge3D node for additional lighting and eventual connection to a Renderer3D node.
