blender_nodetree_stats

This is just a python script to get some stats on nodes in a Blender material nodetree. It counts the nodes, the node types and the max deep level for group nodes.

In this folder you'll find:

the standalone script in the file blender_nodetree_stats.py;
a blender file for directly testing it (blender_nodetree_stats.blend) with:
- a Text Editor window with the script;
- a Text Editor window with some instructions;
- a Python Console window;
- a Shader Editor window with a test material with various levels of nodes and group nodes.

The script will be improved but I wanted to publish it just as it is now. When executed it will print the stats in the console, so if you ran Blender in a console (eg Bash, Windows Command Prompt, Mac Terminal) the stats will appear there. Otherwise you'd run the script from the Python Console window within Blender:

bpy.data.texts['Material Nodetree Stats'].as_module()

If you're using a script in a Blender file other than the test file in this folder, you'll have to replace 'Material Nodetree Stats with the name of the text data-block you copied the script in.

You'll also have to change the material name (3rd line of code in the script) in order to get stats about a material you want to get info about.

It will print a tree-like ASCII representation of the nodes and a python dictionary with all the statistics.
