Adding a Mesh

You can add a basic USD mesh to an empty scene or an existing USD scene. This enables you to develop your USD scene and make live lighting and material changes.

To add a mesh to an existing USD scene:

Right-click on an existing object in the Scene Graph panel.

Select Add Mesh and select the shape.

This will create a mesh that is a child of the object you right-clicked.

To add a mesh to the base level of a scene:

Right-click in the Scene Graph outside the list of existing objects.

Select Add Mesh and select the desired shape.

This will create a mesh on the base level of the Scene Graph.

Each mesh will be created with a white texture. This can be edited using the texture override workflow.

When the object is created, it automatically contains one Material property. Within the Material property there are three Shader properties. Details of these properties are in the Mesh Properties Panel section.

Adding meshes like this is an easy way to add and edit 3D lightcards. They can be used with the Lightcard node to get the right effect (such as the blur effect in the image below). They can also be used for creating cards for standard sequences, or spheres for 360 sequences.

The types of mesh supported currently are:

• Plane

• Cube

• Sphere

• Cylinder

Mesh Properties Panel

When you create a new Mesh, you can access its features by clicking on the dropdown menu next to the Mesh name. Each Mesh has a Material property that contains UVs, Texture and Surface.

In the Properties panel for each of these Mesh features, you are able to separately edit the visibility of the feature, as well as its transform settings. This enables you to fully customize the Mesh to your USD scene.
