usdview opens with blank viewport, usdrecord works

[david-dot-nelson-2-at-sony-dot-com]

Description of Issue

Hi, I am having issues with usdview after compiling where any usd file from examples HelloWorld, to any other usdz I can successfully view in Blender, Maya, and get images with usdrecord, but my viewer is blank I have attempted with Python39 and Python 311. I hope it's something simple. Thanks in advance for the feedback and guidance. -David.

Steps to Reproduce

1. Downloaded latest git repo
2. where python (C:\Program Files\Python39\python.exe)
3. python -m pip install pyopengl
4. python -m pip install pyside6

Is it possible that you have previously overridden some usdview settings, e.g. near clip plane?

What happens if you try: usdview --defaultsettings Sphere.usda?

Encountered this same issue today. Which NVIDIA driver version do you have installed? I had the latest (551.86); changed it to 537.42 (obtained from here: https://www.nvidia.com/Download/Find.aspx?lang=en-us) and the viewport is no longer blank.

[davidgyu]

Oh very interesting. This was working fine for me w/ 551.32 (Jan 24) but I also am able to repro w/ 551.86 (Mar 19). Let me see what I can find out...

[davidgyu]

After some additional testing it seems the essential difference here is PySide2 vs PySide6.

PySide2 support is coming to an end (i.e. it's not available on PyPI for Python 3.11), but it's still what we use for our Python 3.9 testing.

We depend on PySide6 for macOS builds since that's the first release of PySide with support for Apple Silicon, and we've been working to get to parity between PySide2 and PySide6 across the board but we're not fully there yet.

I've been able to test that building OpenUSD on Windows 10 with Python 3.9 or 3.10 and PySide2 5.15.2.1 works as expected w/ the latest NVIDIA 551.86 drivers (and latest AMD or Intel drivers) on recent HW e.g. NVIDIA RTX 4080 (or AMD 7900 XTX or Intel 13900K UHD 770 respectively).

If you have both PySide2 and PySide6 installed, you can coerce build_usd.py to use PySide2 by specifying --build-args USD,"-DPYSIDE_USE_PYSIDE2=TRUE" or similar if you invoke CMake directly.

That was same results unfortunately.

I will give this a try. I have had some conflicts with Houdini 20.653 and usd python from this installation as well from Python 3.9 after compiling USD from the repo here and making it available via sys path.

I will attempt with Python 3.11 since it is in parity with Houdini and your description of current libraries supported.

FWIW, I had no issues with Python 3.11 on Linux and usdview loads fine. I'll post my results later when I get another time slot to do so. Much obliged for your feedback and turnaround. Best regards, -David.

Hey

Was there any solution to this issue yet? As described in: #2996 i have the same issue on Windows with Py3.11 and PySide6 and Nvidia Drivers: 551.86.

Cheers

[davidgyu]

The recommended workaround is to use an earlier version of Qt for Python, i.e. PySide6 6.3.1 or PySide2 5.15.2.1 as described above.

Agree that this seems to be the same bug reported in #2996 and so far has been observed only on Windows when using more recent versions of PySide6.

We describe the versions of software we test with in VERSIONS.md and you can see there that we've still been testing with Python 3.9.x

These recommended versions of PySide appear to work as expected also with Python 3.10 but they are not available on PyPI for Python 3.11 or newer. It seems the broken behavior on Windows started with PySide6 6.4.x.

Thanks!

[davidgyu]

It looks like there is an issue with glDepthMask state in recent versions of PySide6 and that is the reason for the blank viewport. We've merged a fix internally that works around this issue and we've been able to test with Python 3.11 and PySide6 6.7.1.

This issue will be updated when that workaround is pushed out to GitHub.
