# UsdStageDefine

The UsdStageDefine node enables you to set up stage-specific parameters before starting to build your stage in USD.

If you are using a custom ArResolver in their production, this allows you to provide additional data to the resolver for use during asset path resolution.

# Inputs

Connection Type | Connection Name | Function
This node has to be set at the top of the node graph, hence this node has no inputs.

# Controls

Control (UI) | Default Value | Function
--- | --- | ---
populationMask | N/A | Sets the population mask for the stage. The Prim paths will make up a population mask of the prims populated in the stage. If this is empty, we do not apply, and clear, any population mask on the stage.
assetResolverContexts | N/A | The Asset Resolver 2.0 contexts provided to a stage in order to process Asset Resolution within the context set with this stage. Stored as a list of pairs. The first element in the pair is the URI/IRI scheme for the ArResolver that will be used to create the ArResolverContext from the second element in the pair. An empty resource identifier scheme will utilize primary resolver.
