Plugin Factory Verification Failure in adsk/feature/wasm Branch with Emscripten Build

[xiejiashu]

Description of Issue

Hello,

I encountered an issue while building and running the adsk/feature/wasm branch of the USD project. Here are the details:

1. Build Command: I used the following command for building:

   python3 ./build_scripts/build_usd.py --emscripten ./build_dir

2. Build Tool: The build was performed with the emscripten option.

3. Error Message: When running the project, I encountered the following error while loading certain plugins:

   
   Coding Error: in _FindAndInstantiateDiscoveryPlugins at line 928 of /mnt/d/USD/pxr/usd/ndr/registry.cpp - Failed verification: 'pluginFactory'
   ### Error Screenshots

   - ![Error Screenshot 2](sandbox:/mnt/data/image.png)

Environment Information

• Operating System: Windows 11
• Build Tool: emscripten
• Build Command: As mentioned above

Problem Description

During the build and runtime, the system throws an error in the _FindAndInstantiateDiscoveryPlugins function in the registry.cpp file, indicating a failed verification of the plugin factory. This error occurs when loading materials and affects the overall rendering performance.

I would appreciate any guidance or solutions to resolve this issue.

Additional Information

• All dependencies and build environments have been checked and verified to be correct.
• The same build method does not produce similar issues in other branches.

Thank you for your assistance.
