Viewport in usdview does not display geometry
krzykli opened this issue · comments
I've rebuilt USD on Win 7 and #7 is gone. Good stuff!
Unfortunately, the viewport in usdview doesn't render anything. Here's what I get in the console:
λ usdview HelloWorld.usda
Could not parse application stylesheet

Is this happening to anyone else?
[ Edit ] If I disable /hello/world location the viewport seems to work just fine.
Thanks,

Plus the alternate background color in the tree widget looks slightly off. In the log above you can see
Could not parse application stylesheet but when loading the same qss file in Qt Designer everything looks correct, or at least it seems so.
Does the fix in your repo resolve the issue? krzykli/USD@980e5b5
Yes, I looked into this and fixed it locally. I'll submit a pull request shortly.
Of course this just fixes the style sheet issue.
Edit:
PixarAnimationStudios/OpenUSD#113
It's working on Windows 10. Is it possible that your GL driver does not support a recent enough version for Hydra? Hydra needs GL4.3+. Can you try running usdview with the simple render command line option? That should make it run without GL4 features.
Thanks for confirming that @vfxpro99.
I have GL4.3 and the viewport was drawn correctly only when I deactivated the primitive (so I could see the bounding box). Anyway, updating Nvidia drivers did the trick for me so if anyone else hits this you might want to do the same :)
Closing.
Great news :)
