NVIDIA NCP-OUSD Exam Syllabus Topics:

Topic	Details
Topic 1	Customizing USD: Covers extending USD functionality through plugin development, including custom schemas, file format plugins, model kinds, and variant fallback selections.
Topic 2	Content Aggregation: Covers building modular, reusable components and using instancing strategies to efficiently assemble and override assets in large, optimized scenes.
Topic 3	Pipeline Development: Covers high-level pipeline design tasks including asset management, versioning, USD exporter hooks, build configurations, and dependency management.
Topic 4	Data Exchange: Covers creating data mapping documents and building custom importers, exporters, and scripts to interchange data with OpenUSD pipelines.
Topic 5	Composition: Covers authoring, designing with, and debugging all composition arcs (LIVERPS), including understanding when and how to apply each arc in complex scenarios.

NO.15 Which arc is the weakest in LIVRPS ordering?

Variant

Reference

Payload

Specialize

NO.16 What is the fundamental data type in USD that enables API schemas to be non-destructively removed in stronger layers?

list ops

arrays

booleans

NO.17 Which material authoring choice matches MTL better?

UsdPreviewSurface with metallic workflow

UsdPreviewSurface with specular workflow

Only displayColor

No shader graph

NO.18 What type is used to set a display color attribute?

Float

String

Color3f array

Int

NO.19 What is the role of the default prim in encapsulated assets?

To generate all variant sets

To serve as the entry point when the asset is referenced or payloaded

To enforce local opinions

To convert references into payloads

NO.20 Consider the following prim hierarchies. Each prim hierarchy is represented by nested unordered lists and each list item represents a prim with the following format: PRIM_NAME (KIND). No text within the parentheses means that the kind is unset for that prim. Only evaluate model kind hierarchy correctness and the structural choices. Which prim hierarchies represent valid model kind hierarchies? Choose three.

CarA (component)
Interior ()
SteeringWheel ()
Chasis ()
Wheels ()
Wheel_FR ()
Wheel_RL ()

CarA (assembly)
Interior (group)
SteeringWheel (component)
Chasis ()
Wheels (group)
Wheel_FR (component)
Wheel_RL (component)

CarA (component)
Interior ()
SteeringWheel (component)
Chasis ()
Wheels ()
Wheel_FR (component)
Wheel_RL (component)

CarA (component)
Interior ()
SteeringWheel (subcomponent)
Chasis ()
Wheels (group)
Wheel_FR (subcomponent)
Wheel_RL (subcomponent)

CarA (component)
Interior ()
SteeringWheel (subcomponent)
Chasis ()
Wheels ()
Wheel_FR (subcomponent)
Wheel_RL (subcomponent)

NO.21 Which is the correct way to define a Cube under /World?

Usd.Cube.Create(“/World/Cube”)

UsdGeom.Cube.New(“Cube”)

stage.AddPrim(“Cube”)

UsdGeom.Cube.Define(stage, “/World/Cube”)

NO.22 Which of the following values are valid for imageable purpose? Choose three.

guide, for prims that should be included for guides or reference

light, for prims that should be included for lighting and shadows

render, for prims that should be included for “final” quality renders

material, for prims that should be included for shading geometry

proxy, for prims that should be included for proxy representation

NO.23 Which integrity check is essential for faces?

sum(faceVertexCounts) == len(faceVertexIndices)

len(points) == len(normals) always

len(primvars:st) == len(faceVertexCounts)

len(points) == len(faceVertexCounts)

NO.24 Which of the following statements about Subcomponents is correct?

They are formal kinds in OpenUSD

They mark important prims inside a Component

They can exist outside of Components

They act as assemblies

NO.25 Which method retrieves the pseudo-root prim of a stage?

stage.GetRoot()

stage.GetDefaultPrim()

stage.GetPseudoRoot()

Usd.Prim.GetRoot()

NO.26 Which of the following are immutable once a USD Stage has been opened? Choose two.

Rules for loading payloads from prims in the stage.

Layers that are muted or unmuted in the stage.

The path resolver context that is bound to the stage.

Variant fallbacks for prims without variant selection in the stage.

NO.27 Which principle ensures assets load and run efficiently?

Performance

Navigability

Legibility

Modularity

NO.28 Which is not one of the common ways to add OpenUSD support?

Importers

Exporters

Standalone converters

Translators

NO.29 Why is it useful to separate shading and geometry into different workstreams even for a single artist?

Because USD forbids combining them

Because different DCC tools might be used for each

Because materials are always heavier than geometry

Because shading layers cannot be referenced

NO.30 What method is used to assign a new value to an existing attribute in USD?

Get()

CreateAttribute()

Set()

Define()

NO.31 What does the NamespaceEditor.ReparentPrim() function do?

Deletes a prim

Moves a prim under a new parent prim

Renames a prim

Creates a new layer

NO.32 You are a developer creating an OpenUSD exporter for an application that also supports import of USD assets. To enable collaborative workflows, you’re adding an “export as overrides” option.
Which approach correctly describes which structure your exporter should generate?

Overs of the prims and properties that have been modified or added, omitting unchanged data.

Export each prim separately into multiple layers, and reference them individually to maintain sparsity.

Include explicit definitions of all prims, properties, and relationships exactly matching the imported asset to ensure consistency.

NO.33 Referring to dining_room.usda, which of the following best describes the role of the references composition arc on the /Root/Chair prim?
#usda 1.0
def Xform “Root”
{
def Xform “Chair” (
references = @chair.usda@
)
{
float3 xformOp:scale = (1.5, 1.5, 1.5)
}
}

It creates a bidirectional link between the local /Root/chair prim and chair.usda so that any changes in one are automatically reflected in the other.

It is used to import variant sets from chair.usda into the local /Root/chair prim.

It completely replaces the local /Root/chair prim with the contents of chair.usda, ignoring any local attribute definitions such as scale.

It composes the definition from chair.usda with the local /Root/Chair. The local xformOp:scale overrides corresponding referenced opinions.

NO.34 Why is separating geometry.usd and shading.usd useful?

To make the file unreadable

To let geometry and shading artists work independently

To reduce all payloads

To avoid using sublayers

NO.35 What can a variant set define besides overriding properties?

New descendant prims

Sublayer order

LIVRPS ordering

Payload strength

NO.36 What is the main difference between variant sets and primvars in parameterization?

Variant sets are continuous, primvars are discrete

Variant sets are discrete, primvars are continuous/interpolatable

Variant sets cannot be lofted, primvars always must be lofted

Variant sets require Sdf API, primvars require no API
