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 a payload has opinions that may be overriding the opinions from the referenced asset.
• B.Whether the referenced asset has the valid model kind set to maintain a proper model kind hierarchy.
• C.Whether the prim has any variant selections active that might be hiding or overriding the referenced content.
• D.Whether the reference path is correct and the referenced asset exists at that location.

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.Set the defaultPrim in cars.usda
• B.Explicitly set the prim type for car01 in parkingLot.usda
• C.Add a target prim to the reference in parkingLot.usda
• D.Make the ParkingLot prim in parkingLot.usda an assembly kind

• D.By statically merging all possible variants into one combined representation.
