質問 # 41
In OpenUSD, which USDA snippet correctly uses a payload to reference an external asset while allowing deferred loading?
正解：B
解説：
Option A is the correct USDA pattern because a payload is authored as prim metadata using the singular payload keyword with a list-editing operation such as prepend. NVIDIA's Learn OpenUSD payload exercise shows the canonical USDA form: prepend payload = @./red_cube.usd@, authored on the prim declaration. It further explains that payloads are similar to references in USDA, with the important distinction that the keyword is payload rather than references.
The key technical purpose of a payload is deferred loading. NVIDIA explains that payloads can compose scene description when loaded, or unload the targeted scene description beneath the payloaded prim. It also contrasts this with references, which are always composed and present on the stage, while payloads can be opened unloaded and selectively loaded later.
Option B is incorrect because payloads is not the USDA keyword and it is not authored as a property inside the prim body. Option C uses a reference, not a payload, so it does not provide payload load/unload behavior.
Option D is not the canonical list-op form expected here. This aligns with Composition # References and Payloads # Working With Payloads .
質問 # 42
As part of a data exchange workflow, you have exported the following file from your DCC tool, and notice that the displayed extents box of the sphere is too large:
#usda 1.0
(
defaultPrim = "Model1"
)
def Sphere "MySphere"
{
double radius = 0.5
float3[] extent = [(-3.0, -3.0, -3.0), (3.0, 3.0, 3.0)]
}
Your tool, and also the final consumer of the scene data, would like best-fit correct extents. Which of the following could the export process do to address this problem for any exported boundable prim?
正解：D
解説：
The exporter should validate and correct authored extent values on every exported UsdGeomBoundable prim.
The extent attribute is the local-space bounding range of the authored geometric primitive, and if it is authored incorrectly, clients that trust the authored extent can display oversized or inaccurate bounds. NVIDIA's asset- requirements documentation states that "Boundable geometry primitives should have valid extent values," and its compliance guidance says to author extent for boundable geometry and compute it at time samples where geometry-affecting attributes change. ( docs.omniverse.nvidia.com ) Option B is correct because it preserves the intended best-fit bounds and works consistently for any exported boundable prim. Option A is unreliable as an export strategy: OpenUSD may compute extent through registered compute functions when no extent is authored, but this can be expensive and is not a substitute for correct exported data. The OpenUSD UsdGeomBoundable documentation strongly encourages proper authoring of extent. ( openusd.org ) Option C is incorrect because extentsHint is not the replacement for per- primitive boundable extent. Option D is unrelated to geometric bounds. This aligns with Data Exchange # Validation, Geometry Export, Boundable Extents, and Data Quality .
質問 # 43
Why might you choose a payload instead of a reference in rare cases?
正解：D
解説：
Payloads are weaker than references and support deferred loading, which can be beneficial in specific workflows.
質問 # 44
Which transformation order is most commonly used?
正解：B
解説：
Translate → Rotate → Scale (T→R→S) is the typical transformation order.
質問 # 45
Why use Tf.MakeValidIdentifier for prim/material names?
正解：B
解説：
It fixes invalid characters and leading digits.
