Blender 2.66: Addons
New: EDL Import (Video)
The EDL import support has been updated to support recent blender versions (was last included in 2.49).
New: F2 (Modeling)
This addon extends Blender native functionality of creating faces.
It allows to create a face from a single vertex selection or a single edge selection, while retaining all the built-in functionality.
New: MS3D (MilkShape 3D)
This addon supports import and export of MS3D files with meshes, uv maps, materials, armatures, animation and comments. MS3D properties and smoothing groups are exposed to the to Blender user interface to be able to tweak the export of MS3D files.
OBJ now supports import and export of Ngons.
For addon developers: if you were using template_list or callback_add/callback_remove in previous version of Blender, you’ll have to update:
Region Draw Callbacks
To avoid errors on accessing blend-file data while addons register() / unregister(), Blender now restricts access to bpy.context and bpy.data.
This is done because there is no assurance that the data loaded when the addon is registered will be active or even exist when the user accesses operators the addon defines.
If you see an exception like this, then the addon needs to be updated to access the context during execution rather then on registration.
