uszip broken ?

[zhoub]

Description of Issue

Regression of usdzip commandline

Steps to Reproduce

The following command line which creates USDZ package

usdzip --arkitAsset Cone.usdc Cone.usdz ColorMap.png

always reports

usdzip: error: Specify either inputFiles or an asset (via --asset or --arkitAsset, not both.

18.03 worked.

Consider the source code

    if args.asset and args.arkitAsset:
        parser.error("Specify either --asset or --arkitAsset, not both.")

    elif (args.arkitAsset or args.asset) and len(inputFiles)>0:
        parser.error("Specify either inputFiles or an asset (via --asset or "
                     "--arkitAsset, not both.")

It means when arguments contain arkitAsset or asset with external files, it reports error, this is an strange logic.

Hi Bo, I don’t think the logic is strange, and the error tells you the problem, though possibly we could provide a deeper explanation.

With —asset or —arkitAsset, we perform dependency analysis on the single given USD file, finding and including all the USD and image files that it references, recursively. So there’s no need to include any other files on the command line, we believe.
