Omniverse Export Content

Export Content uses maya-usd to export the current Maya Scene or Selection as a USD file to your PC or Omniverse Nucleus.

Any USD proxy nodes in the scene will not be exported, refer to Autodesk Maya Documentation to determine which nodes are supported. If you’re trying to modify the proxy USD stage, then use Save Content instead of Export Content.

Export Options

Menu Item	Description
Export Mode	Export Modes. Prop: Export all data. Prop Animation Clip: Export only animation. Skeletal Mesh: Export skeletal meshes. Skeletal Animation Clip: Exports only skeletal animation clips. Animated Point Cache: Export point cache geometry, baking animation and deformation into the geometry per frame.
Checkpoint Comment	Add a Nucleus checkpoint comment.

*Refer to Autodesk’s docs for supported nodes and attributes

Output

Menu Item	Description
.usd File Format	Binary or Ascii
Create USD Parent	The name of the USD node that is the parent of the exported data. The default is World
USD Parent Type	Xform or Scope. The USD node type of parent, default Xform
Export Roots	Multi-flag that allows export of any DAG subtree without including parents
Move To Origin	All root-level nodes are centered at the origin in the output USD file.

File Output

Menu Item	Description
Batch Export	If References or Payloads are chosen, individual USD scenes will be added to the exported file either as References or Payloads, respectively.
Preset	Sets the preset mode for the exported Maya material
Prop Path	Sets the prop path for the exported Maya material
Material Path	Sets the material path for the exported Maya material
Texture Path	Sets the texture path for the exported Maya material

Export

Menu Item	Description
Lights	Export Maya lights
Cameras	Export Maya cameras
Filter Constraints	Filter constraints, which aren’t supported in USD and can cause translation issues.

Geometry

Menu Item	Description
Subdivision Method	Binary or Ascii
Component Tags	Exports component tags
Color Sets	Enables or disables the export of color sets
UV Sets	Enables or disables the export of UV sets
Skeletons	Determines how to export skeletons. Valid values are: None: No skeletons are exported Auto: All skeletons are exported, SkelRoots may be created Explicit: Only skeletons under SkelRoots are exported
Skin Clusters	Determines how to export skinClusters via the UsdSkel schema. On any mesh where skin bindings are exported, the geometry data is the pre-deformation data. On any mesh where skin bindings are not exported, the geometry data is the final (post-deformation) data. Valid values are: None: No skinClusters are exported Auto: All skinClusters will be exported for non-root prims. The exporter errors on skinClusters on any root prims. The root-most prim containing any skinned mesh will automatically be promoted into a SkelRoot, e.g. if </Model/Mesh> has skinning, then </Model> will be promoted to a SkelRoot Explicit: Only skinClusters under explicitly-tagged SkelRoot prims will be exported. The exporter errors if there are nested SkelRoots. To explicitly tag a prim as a SkelRoot, specify a USD_typeNameattribute on a Maya node.
Blend Shapes	Enables or disables export of blend shapes
Display Colors	Exports display color

Materials

Menu Item	Description
Material Scope Name	Name for the parent scope for material/shader prims.
MDL	Export materials to MDL.
USD Preview Surface	Export materials to USD Preview Surface.
Collect Resources	If checked, copy all textures and materials to the folder containing the exported file.

Animation

Menu Item	Description
Animation Data	Toggle to export animation or not.
Frame Range	Start and end frames to include in the export.
Use Animation Range	Set the start/end frames to match current scene range.

Advanced

Menu Item	Description
Visibility	Exports any state and animation on Maya visibility attributes
Instances	Enables or disables the export of instances
Merge Transform and Shape nodes	Combines Maya transforms and shapes into a single USD prim that has transform and geometry, for all “geometric primitives” (gprims). This results in smaller and faster scenes. Gprims will be unpacked back into transform and shape nodes when imported into Maya from USD.
Include Namespaces	Includes or Removes namespaces during export. By default, namespaces are exported to the USD file in the following format: nameSpaceExample_pPlatonic1
Filter Types	Maya type names to exclude when exporting. If a type is excluded, all inherited types are also excluded, e.g. excluding surfaceShape will exclude mesh as well. When a node is excluded based on its type name, its subtree hierarchy will be pruned from the export, and its descendants will not be exported.
Encoded Options	‘;’ delimited string of additional options supported by maya-usd
