Question #1

Suppose you had the following layer:
#usda 1.0
(
defaultPrim = "ParentXform"
)
def Xform "ParentXform"
{
def Mesh "ChildMesh"
{
}
}
If you wanted to add a property to "ParentXform" such that it would automatically propagate to "ChildMesh" without having to add the same property to "ChildMesh", which of the following changes to "ParentXform" would make this work?

A. Add the property as a primvar, with "constant" interpolation:
string primvars:myProperty = "TestValue" (
interpolation = "constant"
)

B. Add the property as a relationship to < /ParentXform/ChildMesh > :
rel myProperty = < /ParentXform/ChildMesh >

C. Add the property as a custom attribute:
custom string myProperty = "TestValue"

Question #8

When prioritizing ease of interchange and reducing dependencies between different applications in a pipeline, why might codeless schemas, schemas defined purely in .usda files, be preferred over codeful schemas, schemas with generated classes using usdGenSchema?

A. Codeless schemas provide more convenient, strongly-typed C++ and Python APIs for property access compared to code generated via usdGenSchema.

B. Only codeless schemas are added to the schema registry, allowing them to participate in property value resolution correctly.

C. Codeless schemas enable interchange by loading .usda definitions directly, avoiding the need to compile or link against custom schema code libraries.

D. Generated schemas cannot define fallback attribute values within their .usda definition, making interchange less consistent across applications.
