問題 #44
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?
答案：D
解題說明：
The correct method is my_prim.GetAttribute("size") because the question asks for a specific attribute , not a relationship or generic property. NVIDIA's Learn OpenUSD material defines properties as the data-bearing namespace objects on prims and distinguishes two property categories: attributes and relationships .
Attributes hold typed values, while relationships point to other objects in the scene description. NVIDIA's Omniverse developer reference also states that Usd.Prim.GetAttribute() returns a Usd.Attribute, after which Usd.Attribute.Get() is used to resolve the actual authored or composed value.
Option A is therefore the precise API call. Option B is incorrect because GetRelationship() retrieves relationship properties, not value-bearing attributes. Option C is less specific: GetProperty("size") can retrieve either an attribute or relationship as a generic UsdProperty, requiring additional type handling. Option D is incorrect because primvars are accessed through schema-specific APIs such as UsdGeom.PrimvarsAPI, not directly as a general Usd.Prim method. This aligns with Pipeline Development # USD Python API, Property Access, Attributes, Relationships, and Scenegraph Authoring .
問題 #45
What is the correct prim type in UsdShade for sharing reusable portions of shading networks, allowing for parameterization?
答案：C
解題說明：
The correct UsdShade prim type is NodeGraph. NVIDIA's Learn OpenUSD material introduces UsdShade as the schema family used for creating and binding materials, where materials store renderer-facing shading definitions. The OpenUSD UsdShade specification defines UsdShadeNodeGraph as the mechanism for packaging shading networks into reusable units. A node graph can contain shader nodes and nested node graphs, expose public inputs as an interface, provide outputs, and be referenced into larger networks as a reusable building block.
Option C is correct because NodeGraph is explicitly designed for reusable and parameterized shading- network structure. It allows a pipeline to encapsulate repeated shading logic while exposing only selected parameters to consuming materials or larger graphs. Option A is incorrect because SubNetwork is not the correct UsdShade prim type in OpenUSD. Option B is incorrect because a custom schema could theoretically define new data models, but it is not the standard UsdShade construct for reusable shader-network packaging.
This aligns with Visualization # UsdShade, Materials, Shading Networks, NodeGraph Interfaces, Parameterization, and Reusable Material Components .
問題 #46
Why use Tf.MakeValidIdentifier(name)?
答案：A
解題說明：
It sanitizes invalid characters and leading digits.
問題 #47
What commonly breaks when referencing an unencapsulated asset whose Looks scope lives outside /World?
答案：A
解題說明：
If Looks is outside the referenced root, those materials are not grafted, so bindings resolve to nothing.
問題 #48
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.
答案：A,B,C
解題說明：
The valid model kind hierarchies are A, B, and E . NVIDIA's Learn OpenUSD material defines group, assembly, and component as model kinds, while subcomponent is explicitly outside the model hierarchy. The hierarchy rule is that all ancestors of a component must be group or a subkind of group, such as assembly, and a component acts as a leaf or pruning point in the model hierarchy; therefore, it cannot contain descendant model kinds such as another component, group, or assembly. ( NVIDIA Docs ) A is valid because CarA is a component and every descendant has unset kind, so no nested model violates the component boundary. B is valid because CarA is an assembly, organizational containers use group, and the leaf model assets are component prims. E is valid because CarA is a component, and internal important parts are marked as subcomponent, which is permitted inside a component and does not count as a model kind. C is invalid because a component contains descendant component prims. D is invalid because Wheels (group) appears under a component, placing a model kind below a component boundary. This aligns with Content Aggregation # Asset Structure # Model Hierarchy # Model Kinds .
