Review Remaining Validation Issues

There are a few remaining issues to note that are specific to the concept car asset. Other assets may trigger other rules. Refer to the documentation for the Asset Validator for more information.

  1. WeldChecker - This rule checks if there are any co-located, unwelded vertices in the geometry. This issue is addressed in the following section, Merging Unwelded Vertices.

  2. UsdDanglingMaterialBinding - This indicates there are prims in this stage that have materials bound to them, but those materials do not exist in the stage. For some stages, this is a valid issue and may indicate a broken file path; however, in this case, this occurs because DELTAGEN does not introduce those materials until they are referenced in the ConceptCar_3xf_variants.usdc file. It is acceptable to ignore this issue for now because this issue will resolve itself in the later workflow phases.

  3. IndexedPrimvarChecker - This issue notes there is a primitive variable named β€œst” on many of the prims that is not being properly indexed. This causes the prim to be stored inefficiently and incurs some extra overhead. This issue is fixed in a later section, Optimizing Primvars.
