This extension was previously bundled with Blender 4.1. It has now been completely rebuilt, with major improvements.
Node Editor -> Sidebar -> Arrange
Organise your nodes with this auto-layout add-on. No matter the node tree complexity, nodes will be pleasingly arranged, organised, and aligned. You choose what to arrange – select specific nodes or the whole node tree. Adjust settings like spacing and balancing to suit your taste.
Fixes
This extension does not require special permissions.
I got this error: ^^^^^^^^^^^
File "C:\Users\W\AppData\Roaming\Blender Foundation\Blender\4.3\extensions\blender_org\node_arrange\utils.py", line 18, in get_ntree return space.edit_tree ^^^^^^^^^^^^^^^ AttributeError: 'SpaceView3D' object has no attribute 'edit_tree'
All you gotta say is if is instant space and if so then return it that'll totally fix it.
Thanks for keeping this supported and for all that you do for people by providing it!.
