Question #24

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. Make the ParkingLot prim in parkingLot.usda an assembly kind

B. Set the defaultPrim in cars.usda

C. Add a target prim to the reference in parkingLot.usda

D. Explicitly set the prim type for car01 in parkingLot.usda
