City sample in houdini can't process and export

Note that I’m not using PDG, as that failed for some reason I don’t recall.

Export Process:

  • Had to copy freeway_export module to the Houdini install due to using Python 3, so it goes in <install_dir>\python39\libs (might need to put it in python37 if you are using an earlier version). I edited it to replace “print message” with “print(message)”.

  • One of the freeway export nodes calls “reload”, you’ll need to update this to import the reload function by putting “from importlib import reload;” before the rest of it. Note the semicolon to separate the statements. It’s in a callback (so a single-line field) in the node.

  • Had to add the ROOF_ARBITRARY_SHAPE to the export as noted above, copy the TYPE_14 attributes wrangle.

  • For me there was another issue which was an error thrown due to not finding the “mantle” sample files, I was able to fix this by selecting the Alembic node for the mantle sample files and clicking Save to Disk in its details window.

Once those are fixed I was able to do the export/import portion of the tutorial in the documentation normally. Hopefully the roof fix worked, I haven’t seen it complete yet.

If anyone is interested I can make a video of the whole process of fixing it so that it’s easier to follow.

Edit: Roofs still missing
