Error when using cc0assetloader.

Hi, script number 7 (as well as 8,9,10 and 12) fail with this error:

Blender 2.80 (sub 75)
Traceback (most recent call last):
  File "/home/david/coding/blender-cli-rendering/./07_texturing.py", line 66, in <module>

    nodelayout.arrange_nodes(node_tree, use_current_layout_as_initial_guess=False)
AttributeError: module 'nodelayout' has no attribute 'arrange_nodes'

Do I need to install something to make it work?

Thank you for asking!

This repository uses git submodule to include a dependency, cc0assetsloader https://github.com/yuki-koyama/cc0assetsloader, and so just using git clone or downloading as a zip file does not work.

Also, cc0assetsloader uses git lfs, and so it is more complicated.

I guess the directory ./blender-cli-rendering/external/cc0assetsloader is empty currently. Or, ./blender-cli-rendering/external/cc0assetsloader/nodelayout is empty.

One straightforward solution is to

• install both git and git-lfs,
• clone this repository with --recursive option (https://stackoverflow.com/questions/3796927/how-to-git-clone-including-submodules), and then
• run the scripts.

Another possible solution, which is probably easier, is to

• download cc0assetsloader directly from https://github.com/yuki-koyama/cc0assetsloader/releases/download/0-1/cc0assetsloader.zip,
• unzip it,
• replace ./blender-cli-rendering/external/cc0assetsloader with the newly created directory, and then
• run the scripts.

Hope this helps. Sorry for the poor documentation!

Ah, cloning with --recursive did the trick. I had tried 'git submodule init; git submodule update' but that didn't go deeply enough.
