Blend Partially applies edits to a layer’s attributes based on a fractional weight.
Cache Caches the results of cooking the network at different times, increasing playback speed.
Configure Layer Edits metadata on a layer.
Configure Primitive ?
Configure Property ?
Configure Stage Configures metadata for how to load layers into the stage and asset resolution.
Duplicate Creates copies of a prim (and its descendants).
Edit Target Layer Allows you to apply edits directly in a lower layer, instead of overriding prims and attributes in the active layer.
Error Generates a message, warning, or error, which can show up on a parent asset.
For Each The end node of a For-Each loop block.
Inline USD Parses usda code representing a layer and adds it to the layer stack.
Instancer Instances or copies primitives onto points.
Isolate ?
Layer Break Starts a new active sublayer that subsequent nodes will edit.
Layer Replace Replaces all uses of a certain layer with a substitute layer from its second input.
Null This node does nothing. It can be useful to insert a Null into a network as a "fixed point" in the network that you can refer to by name in expressions/scripts.
Output Represents the output of a subnetwork. Allows you to design a node asset with multiple outputs.
Prune Hides or deactivates primitives and point instances.
Python Script Lets you write Python code in the node to use the USD API to directly manipulate the stage.
Set Extents Sets the bounding box metadata of selected primitives.
Store Parameter Values Lets you store temporary (unsaved) data in the stage.
Subnetwork ?
Switch Passes through one of several inputs, based on a parameter choice or expression.
TimeShift Outputs the stage as it is at a different point in the timeline.
Transform UV Moves, rotates, and scales texture coordinates on USD primitives.
