Summary

Each mesh must bind a material named basic_material.

Description

This example requirement demonstrates using generated requirements for a rule that inspects relationships between prims. The validator walks the default prim hierarchy, computes the bound material for each mesh, and reports cap.ExampleRequirements.EX_002 when the material prim is not named basic_material.

Example

# Valid: the mesh is bound to a material named basic_material
def Xform "Asset"
{
    def Scope "Looks"
    {
        def Material "basic_material"
        {
        }
    }

    def Mesh "Body" (
        prepend apiSchemas = ["MaterialBindingAPI"]
    )
    {
        rel material:binding = </Asset/Looks/basic_material>
    }
}

How to comply

Bind each mesh to a UsdShade.Material prim named basic_material.
