GeoSelection

The GeoSelection node allows you to store a face or vertex selection in the Viewer and then reapply the selection to another object. Each selection is stored using the prim's scene graph location, so you can store as many selections as required as long as each selection has a unique path. For example, an 8x8 card with its top row of faces selected and another 8x8 card with all faces selected:

{ /GeoCard1/Card faces 8 1 56 0 facWei 8 1 56 0 }

{ /GeoCard2/Card faces 64 1 facWei 64 1 }

To learn more about the workflow, see Using GeoSelection.

Tip: GeoSelection's classic 3D system equivalent is the GeoSelect node.

Inputs and Controls

Connection Type	Connection Name	Function
Input	unnamed	The previous stage in the scene you want to affect.

Control (UI)	Knob (Scripting)	Default Value	Function
GeoSelection
Mask	mask_patterns	Default - Injected/ All Roots	Specifies the mask pattern to match the prim names to affect. You can use standard glob-style wildcards, such as '', '?', to create masks or use individual prim names separated by spaces. For example, /GeoCube 1 /GeoCard3 applies the effect to only those prims. Default - Injected/All Roots* - selects the default prim(s) for the node. The default will be the injected mask prim paths if there is an upstream node with this. Otherwise the default mask for this node type is evaluated. All roots - select the top level Xform(s) in your scene. Last modified - selects whatever the last node modified was. All Cameras - selects all Cameras in your scene graph. All Lights - select all lights in your scene graph. All Meshes - selects all meshes in your scene graph. Custom - sets a custom selection of prims that exist in your scene graph. Tip: You can also use the cog menu, the Viewer picker, or drag and drop paths from the Scene Graph to create masks.
Inject Mask	inject_mask	off	When enabled the mask in this node is injected into the node directly below it if that node has the default path mask set.
Save Selection	save_selection	N/A	Click to save the currently selected faces or vertices, dependent on the 3D Viewer mode.
Restore Selection	restore_selection	N/A	Click to restore the selected faces or vertices saved in the node.
