Selection Modes

Selection modes in Omniverse USD Composer allow easy access to both Groups of Prims and to Prims themselves.

Changing Selection Mode

In the top of the toolbar you can toggle the selection mode.

Note

You can toggle modes quickly and easily by using the T Hot-Key. Simply press T and the mode will toggle back and forth. You can also use the Q Hot-Key to automatically switch to selection mode.

Model Selection

While in Model Selection, Users can select, move, rotate and scale Prims which have had their Kind metadata set as Component.

Prim Selection

While in Prim Selection, Users can select, move, rotate, and scale the primitives that make up a component.

Managing Selections with Kinds

The meta-data Kinds plays an important role in using the selection tool in Model Mode and can be configured for optimal utility in your scenes.

Kind	Description of Kind	Effect on Model Mode Selection
Assembly	Important Group	Ignored
Group	Group	Ignored
Component	An collection of assets	Top Selectable Kind
Sub Component	An Asset	Force-Selects Parent
None	No Kind Set	Bottom Selectable Kind

This example shows how an asset might be configured for optimal use in Model Mode Selection. In this case, Selecting any of the meshes under Desk Chair will select the parent group “Desk Chair” rather than its individual parts. This adaptable nature allows you to control high order selections in large scenes and projects.

Ref #	Kind Setting
1	Assembly
2	Component
3	Sub-Component or Blank

Selecting Parent Groups in Prim Mode

When in prim mode, you can select a parent group by selecting the containment outline (bounding box).
