MaterialAssign
Assigns materials to geometry in the Scene Graph.
Control (UI) Default Value Function
CEL none Sets the CEL specification of Scene Graph locations on which the
assignment will act.
materialAssign none Specifies the material to assign. Typically, you'll middle-mouse
drag this from under /root/materials/geo in the Scene Graph.
MaterialResolve
Resolves materials in the Scene Graph. At Scene Graph locations with materialAssign attributes, it finds the
material that is referenced and copies its material attributes to the Scene Graph location. Results of this operation
can be viewed in the Attributes tab. It can also be used to apply material overrides set by the Material node.
MaterialStack
MaterialStack node is a specialized GroupStack for organizing your scene Materials. To move a Material node that is
outside the MaterialStack node to inside the stack, hold down the shift key and middle-mouse drag it in.
The Material in the stack are linked together, providing a single output by connecting them one after the other in
serial, in the order in which they appear in the stack. Selecting Materials in the stack displays their controls on the
right of the stack.
Merge
The merge node allows you to combine multiple scenes into a single output scene. All objects in any of the input
scenes are present in the output scene. If a location is present in more than one of the input scenes, then attribute
values are taken from the left most input which has the location (however, the Advanced Options allow more
control over this). Merge is a very versatile node for collecting multiple elements into a scene for rendering.
Tips:
• A merge node with a single input is effectively a no-Op node.
