Free NVIDIA NCP-OUSD Exam Dumps Questions & Answers

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

• A.  dictionaries
• B.  structs
• C.  assset paths
• D.  string arrays

Why is usdchecker an important part of data exchange?

• A.  It verifies that all USD files are in binary format for max efficiency.
• B.  It provides the best assurance that an asset will be consumable downstream.
• C.  It verifies asset URIs are correctly formed for portability.
• D.  It optimizes USD files for faster loading and rendering.

Review the following code for creating 1000 sphere instances. When this code is executed, why will the authored prims not yield any instancing efficiencies?
for i in range(1000):
xform = UsdGeom.Xform.Define(stage, f"/test_{i}")
sphere_path = xform.GetPath().AppendPath("sphere")
UsdGeom.Sphere.Define(stage, sphere_path)
xform.GetPrim().SetInstanceable(True)
xform.AddTranslateOp().Set((i * 2, 0, 0))

• A.  You must also call Usd.Prim.SetInstanceable(True) for each sphere prim that is created.
• B.  There are no composition arcs so the instanceable metadata is ignored.
• C.  Every sphere has a different position so the instanceable metadata is ignored.

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?

• A.  my_prim.GetAttribute("size")
• B.  my_prim.GetProperty("size")
• C.  my_prim.GetRelationship("size")
• D.  my_prim.GetPrimvar("size")

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.  Point instancing generates prototypes dynamically, while native instancing uses statically defined prims.
• C.  Native instancing can only use a single prototype per scene, while point instancing can use multiple prototypes.
• D.  Native instancing requires prototypes to be defined in separate files, while point instancing requires them in the same layer.
