missing pxr imports in Docker moonray_run Container when rendering ALab2 scene

[samhodge]

Followed Docker Container build commands

ALab scene is mounter at /alab in the docker run container

I get the following traceback

from

hd_render -in /alab/entry.usda -out /tmp/hoopla.exr

You can read https://docs.openmoonray.org/user-reference/tools/hydra/hdmoonray-setup/#python-and-hydra-setup.

To get rid of the warnings, you need to add the location of the pxr Python modules to PYTHONPATH. They should be in /usr/local/lib/python:

ls /usr/local/lib/python pxr export PYTHONPATH=/usr/local/lib/python

I don't know if this could be causing the black image though, since hd_render doesn't use python modules.

[kognat-docs]

What could be causing an image to be output with black pixels?

It feels like the geometry is there

Hi @samhodge did you mipmap your textures? Perhaps that's the issue. MoonRay requires tiled textures (see https://docs.openmoonray.org/user-reference/performance/#tiled-textures). To tile your textures you can use maketx or oiiotool .

[samhodge]

Well that is the odd thing, using the convert to the binary moonray format for one entity from the Alab2 asset seems to render OK via moonray_gui as seen below.

But giving the entry point and relying on the Hydra interface gives a "no bingo" result, ie black and 34Kb.
