omni.graph.nodes.ReadPrimBundle Description

Exposes the authored attributes for a single Prim on the USD stage as a bundle output on this node. When this node computes it will read the latest attribute values from the target Prim into the bundle attributes. It will also expose the world matrix if available under the attribute “worldMatrix”. It can optionally compute the bounding box of the prim, and expose it under the following attributes: “bboxTransform”, “bboxMinCorner”, “bboxMaxCorner”.

omni.graph.nodes.ReadPrimBundle Inputs

Name	Type	Default	Required?	Descripton
inputs:computeBoundingBox	bool	False	Y	Compute and store local bounding box of a prim and its children.
	__default	false
inputs:prim	bundle	None		The prim whose attributes are to be read
inputs:primPath	token	None		The path of the prim to be read when ‘usePath’ is true
inputs:usdTimecode	timecode	-1	Y	The time at which to evaluate the transform of the USD prim. A value of “-1” indicates that the default USD time stamp should be used
	__default	-1
inputs:usePath	bool	False	Y	When true, the ‘primPath’ attribute is used as the path to the prim being read, otherwise it will read the connection at the ‘prim’ attribute
	__default	false

omni.graph.nodes.ReadPrimBundle Outputs

Name	Type	Default	Required?	Descripton
outputs:primBundle	bundle	None	Y	A bundle of the source Prim attributes. In addition to the data attributes, there is a token attribute named sourcePrimPath which contains the path of the Prim being read

omni.graph.nodes.ReadPrimBundle State

Name	Type	Default	Required?	Descripton
state:target	uint64	0	Y	The path ID of the targeted prim last frame
	__default	0
state:usdTimecode	timecode	-1	Y	The time at which previous run has been evaluated
	__default	-1
