UsdTransformSet

In USD, a "transform" commonly refers to the spatial transformation of a prim in the scene. Transformations are used to position, orient, and scale prims in 3D space. The main types of transformations are translation, rotation, and scale. You can also set a pivot point from which translation or rotation occurs. To learn more about transformations, see Native USD Transformations.

UsdTransformSet applies a 3D transform to one or more prims as defined by their paths in the USD scene. You can choose to append the transform to existing transforms using appendTransform, or leave it unchecked to overwrite any transforms on that prim.

Enter transform values along the x, y, and z axes for translate, rotate, and scale. You can also enter values for the pivot point for transformations away from the origin by translation and rotation.

The three transformation types can be applied in order as defined by any permutation of scale, rotate, and translate. Select this using the order dropdown.

Note:  UsdTransformSet is the USD equivalent of Transform3D. However, there are differences between the default settings. For example, the stack order in Geolib defaults to "first", whereas the defaults in USD are the opposite.

The UsdTransformSet node also has an option which allows you to use Viewer transform manipulators against USD native scene locations. To use this option, makeInteractive should be set to Yes. See Viewer Manipulators for Native USD to learn more about the workflow.

Inputs

Connection Type	Connection Name	Function
input	in	The incoming scene graph data that the node will operate on or modify.

Controls

Control (UI)	Default Value	Function
primPaths	N/A	The prim locations as described by their paths in the USD scene hierarchy
xformOpName	same as node name	The name given to the node. This is assigned automatically as the node name to make it unique. You can override the default to allow overrides for specific transform Ops. The node name is set using the ‘nodeName’ expression. This can be edited if you prefer.
appendTransform	off	Check this to append the transform to the current list of transforms that are active on the prim(s).  If unchecked, the transform overwrites any existing transforms on the prim(s).
order	Scale Rot Trans	Select the order by which the three transformations are applied.
rotateOrder	Rx Ry Rz	Select the axes order by which the rotation takes place. By default the rotation is first around the x axis, then y, and finally z.
translate	0.0,0.0,0.0	The amounts to translate along the x, y, and z axes.
rotate	0.0,0.0,0.0	The amounts to rotate the prims around the x, y, and z axes.
scale	1.0,1.0,1.0	The amounts to scale the prims along the x, y, and z axes.
pivotTranslate	0.0,0.0,0.0	The amounts by which the pivot point for transformations is translated along the x, y, and z axes.
pivotRotate	0.0,0.0,0.0	Enter the amounts by which the pivot point for transformations is rotated around the x, y, and z axes.
makeInteractive	Yes	When set to "Yes", the selected path can be interactively manipulated in the Viewer. This option is only available when the mode parameter is set to "Single Path".
asMatrix	disabled	If makeInteractive is set to “No”, this option becomes visible, allowing you to set the attributes as a matrix.
