NodeToPython v3.2.1

NodeToPython v3.2.1 has been released! This update contains some minor bug fixes (#125) and other changes for the release on the Extensions Platform

NodeToPython v3.2.0

NodeToPython 3.2 has been released! This update includes updates for Blender 4.2 LTS and additional options. Some highlights from this release:

Features

• New Blender 4.2 nodes and sockets
• Create manifest files for extensions
• Can now set node group color_tag and description properties starting with Blender 4.2
• Script vs Add-on mode creation is now done through the Options panel
• Setting values like node dimensions and group defaults, mins, and maxes is now optional
• Scripts now include import statements by default
• Add-on metadata can now be populated directly from the options panel
• NodeToPython can now package licenses with your add-ons

Fixes

• Images without valid data will now throw warnings, and won't attempt to save or load

General

• New logo!
• The repo has been restructured a little, with a new tools/ directory and all source files in one folder

Pending approval, NodeToPython will also be available on the Blender Extensions Platform starting with v3.2.0, and you'll be able to download and get official updates from there.

NodeToPython v3.1.0

NodeToPython v3.1 has arrived! Here's what's new:

• Blender 4.1 is now officially supported
• Nodes can now set their hide property
• Added compositor node tree settings
• In Blender 4.1 or higher, links to multi-socket inputs will now be ordered correctly
• Node settings are now generated with a script, which has corrected some inaccuracies and will speed up future upgrades with new Blender versions
• Fixed issue where warnings were incorrectly generated for a Blender version

NodeToPython v3.0.1

This release contains some fixes related to packaging generated Python add-ons

See #88 for a full list

NodeToPython v3.0.0

NodeToPython v3.0 is finally here!

Blender 4.0 is now officially supported. NodeToPython has been upgraded to handle Node Panels and the new NodeTree interface, and it now supports Repeat Zones, Geometry Node Tools, the new Rotation socket, and a whole host of new nodes and settings

Joining its Geometry and Shader counterparts, NodeToPython can now generate Compositor Nodes for a scene.

This update includes a bunch of other improvements, including

• More robust variable name creation
• Setting a node's name attribute
• Fixing issues with how subgroups were handled
• A major refactor, which cleaned up the code and should speed up future development

NodeToPython v2.2.0

NodeToPython v2.2 is here! This update is mostly about controlling how and where your Python code is generated.

The new Script mode creates a function to just recreate your node tree in Python code, no extra add-on fluff. It copies the function to your Blender clipboard, where you can paste it inside of the text editor to easily run or insert into your own code.

There's also Add-on mode, which behaves just like previous versions. You can now also set the location where the generated add-on is saved to, no longer forcing an addons/ directory to where your blend file was saved.

This update also includes some minor quality of life improvements and code cleanup.

Full Changelist

Features

• New Script mode, which copies the selected node group to the Blender clipboard
• NodeToPython now alerts users where the script or add-on is saved to when done generating
• Users can now specify a directory to save a generated add-on to
  • No longer auto-generates an addons/ directory
• New NTPOptions property group for global options, namely just the save directory right now
• New NTPOptionsPanel in the NodeToPython menu for setting global options

Fixes

• Fixed typo in generated unregister() functions

Refactor

• More consistent usage of string functions
• Variable names now use a dictionary with (name, usage count) pairs instead of a set

Other

• Generated add-ons now use bl_info category "Node"
• Removed image related print statements

Future

Next I plan on tackling Compositing Nodes, finally adding all of Blender's supported node editors. This'll likely release with support for Blender 4.0's new nodes (including the highly anticipated repeat zone).

NodeToPython v2.1.1

Installation instructions

Changelist

• Shader node group inputs and outputs are now properly generated
• Image nodes no longer throw errors when no image is selected
  Refactor
• All group inputs and outputs now share the same logic for creation and settings
• Renamed node_tree_var to nt_var to make geo_nodes.py consistent with materials.py

Changelist

Features

• More nodes have default values set
