1. What is the only reliable way in OpenUSD of encoding the motion of primitives whose topology is varying over time?

positions

velocities

orientations

2. When USD computes the position of a PointInstancer instance, what additional position-related information is used beyond the position information for a given instance?

USD also uses the transform of the PointInstancer prim, if present, but ignores any transforms set on the prototype root.

USD also uses the transform of the root of the prototype and the transform of the PointInstancer prim itself, if present.

USD uses position information for the instance, and ignores any position information in the prototype root, or the PointInstancer prim itself.

3. When prioritizing ease of interchange and reducing dependencies between different applications in a pipeline, why might codeless schemas, schemas defined purely in .usda files, be preferred over codeful schemas, schemas with generated classes using usdGenSchema?

Codeless schemas enable interchange by loading .usda definitions directly, avoiding the need to compile or link against custom schema code libraries.

Codeless schemas provide more convenient, strongly-typed C++ and Python APIs for property access compared to code generated via usdGenSchema.

Generated schemas cannot define fallback attribute values within their .usda definition, making interchange less consistent across applications.

Only codeless schemas are added to the schema registry, allowing them to participate in property value resolution correctly.

4. Which of the following methods allows you to edit the color of an instanceProxy mesh in OpenUSD while keeping the prim instanced?

Directly modifying the instance's geometry properties.

Using primvars to change the color of the mesh or assigned material.

Creating a relationship targeting the mesh's color attribute.

Replacing the entire instance with a new mesh that has the desired color.

5. Which of the following statements best describes the purpose of OpenUSD file format plugins?

They extend OpenUSD's functionality by allowing it to read and write from various file formats.

They are only used for visualizing OpenUSD data and geometry in 3D applications.

They convert OpenUSD files to other formats without any loss of data or information.

They are designed to compress OpenUSD asset files for faster loading times.

6. If you have a Usd.Prim object named my_prim and you want to specifically retrieve an attribute named "size", which method would you typically use?

my_prim.GetAttribute("size")

my_prim.GetRelationship("size")

my_prim.GetProperty("size")

my_prim.GetPrimvar("size")

7. Which statement correctly describes how UsdGeomSubsets can be used to organize geometry for specific material assignments or rendering attributes in OpenUSD?

They partition a single UsdGeomMesh into distinct groups that can have materials independently bound to them.

They can provide finer-grained control of UsdGeomImageable properties, e.g. visibility or purpose, on subsets of faces.

They force a mesh to be tessellated at the boundary of each subset for improved visual quality.

They must be defined at the root OpenUSD stage level for them to apply to any mesh.

8. In OpenUSD, which USDA snippet correctly uses a payload to reference an external asset while allowing deferred loading?

def "Character" (prepend payload = @character.usda@) { }

def "Character" { prepend payloads = @character.usd@ }

def Xform "Character" (reference = @character.usda@) { }

def Xform "Character" (payload = @character.usd@) { }

9. Why would you not see a sphere when opening this scene?

#usda 1.0

(

defaultPrim = "wall_a_inst"

upAxis = "Z"

)

def Xform "wall_a_inst" (

instanceable = true

variants = {

string Emissive = "Default"

}

prepend variantSets = "Emissive"

)

{

def Sphere "Sphere"

{

}

variantSet "Emissive" = {

"Daytime" {

}

"Default" {

}

}

}

Sphere are guide geometry that are invisible by default.

The "Emissive" variant set is missing the material bindings for both "Daytime" and "Default".

Because "wall_a_inst" has instanceable=true and a composition arc, variants, the sphere that is inside of "wall_a_inst" but outside of its variantset is not part of the instanced scenegraph.

10. Which of these is a viable approach for mapping or grouping compound types from other data

sources to OpenUSD?

arrays

namespace-prefixed attributes

structs

11. 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

12. 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.

13. You and your colleague open the same USD layer but one of you observes missing geometry.

What could be the reason why?

USD automatically adjusts composition based on available system memory.

Instance prototypes are composing to different identifiers.

Differently configured asset resolvers are resolving to different versions of the asset.

14. In what way do variant sets in OpenUSD enhance flexibility in scene descriptions?

By allowing runtime selection among alternative representations of a prim.

By permanently embedding multiple scene configurations within a single prim.

By enabling automatic resolution of conflicting opinions across layers.

By statically merging all possible variants into one combined representation.

15. How does the concept of an edit target (Usd.EditTarget) interact with the stage in OpenUSD?

It merges edits across all layers automatically for simplified editing of a stage.

It overrides all layers, forcing every change to be written to the root layer.

It specifies the destination layer for authoring changes in a composed stage.

It temporarily disables all sublayer compositions during editing.

16. Which of the following statements about OpenUSD plugin development are true? Choose two.

File format plugins are responsible for translating foreign file formats into OpenUSD-compatible data.

Custom plugins can extend OpenUSD by adding new data types and behaviors.

OpenUSD plugins can be developed as Python-only plugins for faster, iterative development.

All plugins require recompiling USD so that they can be used and recognized by US

17. What is the primary purpose of asset structure in OpenUSD?

To simplify version control through standardized asset management and tracking

To maximize rendering performance through optimized data organization and caching

To empower the scalability of an organization and ecosystem and promote collaboration

To reduce storage requirements through efficient resource sharing and deduplication

18. 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.

19. 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)

20. Why is extract, transform, load (ETL) a useful design pattern for USD data exchange? Choose two.

It guarantees that all data converted to OpenUSD is lossless and identical to the original format.

It separates concerns, making it easier to maintain and adapt data exchange pipelines for different needs.

It ensures that all OpenUSD workflows use a standardized data structure, regardless of the original format.

It helps preserve the integrity of the original data format while allowing tailoring for different use cases.

21. Which of these are valid types for custom attributes in OpenUSD? (Choose two.)

structs

assset paths

string arrays

dictionaries

22. When constructing an OpenUSD scene, in which scenario is it most appropriate to use a payload instead of a reference?

When an asset requires frequent updates, but the asset should default to the latest version.

When deferring the loading of heavy assets until they are needed, thereby improving initial load performance.

When the asset is small and inexpensive to load to ensure efficient transfer over web protocols.

When it's important to ensure that all referenced data is immediately available on stage load.

23. What is the correct prim type in UsdShade for sharing reusable portions of shading networks, allowing for parameterization?

SubNetwork

Custom Schema

NodeGraph

24. In what way do variant sets in OpenUSD enhance flexibility in scene descriptions?

By allowing runtime selection among alternative representations of a prim.

By permanently embedding multiple scene configurations within a single prim.

By enabling automatic resolution of conflicting opinions across layers.

By statically merging all possible variants into one combined representation.

25. What key capability distinguishes an IsA schema from an API schema?

An IsA schema can impart a typeName to a prim, whereas an API schema cannot.

API schemas can have relationships, while IsA schemas cannot.

IsA schemas are always concrete, while API schemas are always non-concrete.
