1GB inputs to usdzip generate 2GB usdz file

[jcowles]

Description of Issue

Subject says it all.

Steps to Reproduce

1. Localize files into a directory
2. cd into the directory
3. run "usdzip Volund.usdz ."

First problem, usdzip attempts to zip the temp usdz file: usdzip Volund.usdz . Skipping empty file '.\Volund.vhdmao'.

When complete, the generated usdz file is 2GB, but the source files are 1GB total. Let me know if you want my actual source files.

Sounds like an awesomely pathological alignment bug...

This was due to duplicate archiving, which is fixed in our dev tree, and I believe was the result of commit 9bfcf499715c7b08fabff99959e38e83d7ab20d1 .

Jeremy I'd like to note that your give usdzip command-line won't produce a legit usdz archive... when not using the "--asset" or "--arkitAsset" flags, you must provide the root/default usd file as the first file following the usdz file. I successfully made an archive like so:

usdzip Volund.usdz VolundModel.usda *

We should definitely document this better.
