USD Add Assets to Gallery TOP node

Adds USD assets to the Asset Gallery.

Since 19.0

This node scans the directories specified in the Pattern parameter and looks for the USD asset files. If found, it adds them to the Asset Gallery.

For the asset thumbnail, it uses the file found in each subdirectory. If no thumbnail file is found, it renders one out and uses that for the asset.


Generate When

Determines when this node will generate work items. You should generally leave this set to “Automatic” unless you know the node requires a specific generation mode, or that the work items need to be generated dynamically.

All Upstream Items are Generated

This node will generate work items once all of the input nodes have generated their work items.

All Upstream Items are Cooked

This node will generate work items once all of the input nodes have cooked their work items.

Each Upstream Item is Cooked

This node will generate work items each time a work item in an input node is cooked.


The generation mode is selected based on the generation mode of the input nodes. If any of the input nodes are generating work items when their inputs cook, this node will be set to Each Upstream Item is Cooked. Otherwise, it will be set to All Upstream Items are Generated.


Specifies path pattern for directories in which to look for USD asset files.

Variant Sets

Specifies a comma or space separate list of variant set names which should be traversed on the asset file. For each variant available in each variant set, a separate asset will be created in the gallery.
