HdAurora deployment on Linux and usdview rendering issues

[lindemeier]

Hello there,
thx for publishing this awesome renderer.

Since I want to use USD and Hydra mostly on Linux I gave it a try to run HdAurora on Linux.

Several steps were necessary to build and deploy hdAurora:

1. First of all, the deployHdAurora.py does not support linux for now.
   I've made (quick) adjustments here:
   https://github.com/lindemeier/Aurora/blob/73809a1291b107742ad7c0571606c40242083835/Scripts/deployHdAurora.py

2. The lib in pluginInfo.json needs to be named accordingly:
   https://github.com/lindemeier/Aurora/blob/73809a1291b107742ad7c0571606c40242083835/Libraries/HdAurora/resources/linux/plugInfo.json

3. Upgrade boost to 1.78 due to compilation errors.

After executing these steps I was able to run usdview in a conda environment setup with all python dependencies.

After starting usdview directly with Aurora as renderer and the USD "Kitchen_Set" as input scene, I get the following output:

The terminal is spammed with:

v22.11/pxr/base/vt/value.cpp : 'Attempted to get value of type 'VtArray<GfVec2f>' from empty VtValue.'
        Error in '*pxrInternal_v0_22__pxrReserved__::VtValue::_FailGet' at line 562 in file /home/zotlinde/dev/Aurora/externals/src/USD-22.08-Aurora-v22.11/pxr/base/vt/value.cpp : 'Attempted to get value of type 'VtArray<GfVec3f>' from empty VtValue.'

I tried to run it on the following operating systems:

• Ubuntu 22.04 (native)
• Ubuntu 20.04 (docker image based on a NVIDIA cudagl image). Here step 3 was not necessary, since boost built with no error here (due to the gcc version I'd assume).

Both showed the exact same behavior.

Further information:
I tried gcc and clang-12. No difference.

Hi,

This looks very promising indeed, we have been missing a rasterizer in hydra that can do nice raytraced shadows and reflections. This seems like a great render that fits the gap. However, I'm getting same issue as lindemeier here on Linux Mint.

Tried the new release v23.03.

Now I get these errors (Autodesk Telescope):

Simple test usd scene with a cube and some lights:

AttributeError: 'NoneType' object has no attribute 'isValid'

Segmentation fault (core dumped)

It segfaults directly.

Compiled it with default gcc on Ubuntu 22.04. Will try it with my docker Ubuntu 20.04 setup when I have time.
