出題：2

Consider a task where a Mesh prim needs to have its points property subdivided to achieve a higher quality of deformation. Which of the following is correct?

A. It is impossible to override the points property of the Mesh, since subdivision can only happen at rendertime through the subdivisionScheme attribute of the Mesh schema.

B. Non-constant primvars like displayColor and UVs from the Mesh need to be updated as well, since it is responsibility of the process overriding the points to also provide valid values for other primvars.

C. Non-constant primvars like displayColor and UVs from the Mesh can be left unchanged, since USD handles the resize of the array values to match the points property automatically during composition.

出題：5

Considering the two files cars.usda and parkingLot.usda in the exhibit. When opening a stage with parkingLot.
usda as the root layer, you observed this prim hierarchy:
* ParkingLot
* car01
You expected this:
* ParkingLot
* car01
* chassis
parkingLot.usda:
#usda 1.0
(
upAxis = "Y"
)
def Xform "ParkingLot" (kind = "group")
{
def "car01" (references = @cars.usda@) {}
}
cars.usda:
#usda 1.0
(
upAxis = "Y"
)
def Xform "redCar" (kind = "component")
{
def Mesh "chassis" {}
}
def Xform "blueCar" (kind = "component")
{
def Mesh "chassis" {}
}
What are ways to fix this issue?

A. Make the ParkingLot prim in parkingLot.usda an assembly kind

B. Add a target prim to the reference in parkingLot.usda

C. Set the defaultPrim in cars.usda

D. Explicitly set the prim type for car01 in parkingLot.usda

出題：6

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

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

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

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

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

出題：7

Which statement accurately describes a key difference between native instancing and point instancing?

A. Native instances are individually addressable prims in the scene hierarchy after composition, while point instances are not.

B. Native instancing requires prototypes to be defined in separate files, while point instancing requires them in the same layer.

C. Native instancing can only use a single prototype per scene, while point instancing can use multiple prototypes.

D. Point instancing generates prototypes dynamically, while native instancing uses statically defined prims.

出題：8

In OpenUSD, when composing a stage, why might opinions from one layer not take effect in the final composed stage?

A. The layer is not referenced properly, so its opinions are ignored.

B. The opinions are in a non-editable layer that does not allow modifications during composition.

C. The layer containing the opinion has a lower strength than other layers, and its changes are overridden.

D. The layer containing the opinion does not use the correct schema for the data.
