USD Import Prims TOP node

Creates work items from prims found in a USD stage.

On this page

Reads a USD file, and creates work items from all prims. The search can be done on the flattened stage, the individual root layer, or recursively on the root layer and all sub layers. The retrieved prims are therefore USDPrim or SdfPrimSpec depending if the stage is composed.

TOP Attributes

primname

string

The name of the prim.

primpath

string

The full path to the prim.

Parameters

Work Item Generation

Whether this node generates static or dynamic work items. You should generally leave this set to "Automatic" unless you know the node’s work items can be computed statically, or that they need to be generated dynamically.

Dynamic

This node always creates dynamic work items: it waits until the upstream work items are known, and generates new work items from the upstream work items.

Static

This node always creates static work items: it creates the number of work items it thinks it needs based on the parameters (and any upstream static items) before the network runs.

Automatic

If the input is static (a static processor, or a partitioner with only static inputs, or a mapper), this node generates static work items, otherwise it generates dynamic work items.

USD File

Upstream File: Read from file data on the upstream work item.

Custom File Path: Read from the given file path.

With File Tag

Tag of upstream file data when USD File is set to Upstream File.

Path

Full path to the USD file to be read when USD File is set to Custom File Path.

Resolution Mode

Flattened Stage: The stage is flattened before searching.

Recursive Layer: The stage layers are recursively searched without being flattened.

Single Layer: The layer of the given USD file is searched without following considering sub layers.

Output File Tag

Apply this tag to output file data instead of automatically detecting a tag.
