質問 3

You are debugging a stage where a prim is expected to have opinions from a referenced asset, but those opinions are not appearing in the composed scene. Which of the following are logical things to check to troubleshoot this issue?

A. Whether the referenced asset has the valid model kind set to maintain a proper model kind hierarchy.

B. Whether the prim has any variant selections active that might be hiding or overriding the referenced content.

C. Whether a payload has opinions that may be overriding the opinions from the referenced asset.

D. Whether the reference path is correct and the referenced asset exists at that location.

質問 5

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

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

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

D. timeCodesPerSecond

正解: D

質問 7

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

A. By allowing runtime selection among alternative representations of a prim.

B. By enabling automatic resolution of conflicting opinions across layers.
