Release v1.4.2

Update for breaking API changes in Blender 5.0. There are no functional changes in the add-on.

Release v1.4.1

Regarding paper thickness, concave edges are now supported.

This feature needs yet to be extensively tested on real models and real cardboard. Please report buggy behavior and unexpected results in the issue tracker or directly on my email [email protected].

Also, models with flipped normals are now handled correctly: convex/concave edges are consistent even in most of such cases.

Release v1.4.0

New features are available for testing: paper thickness and JSON export

Paper thickness

It is possible to specify paper thickness that will be compensated in the net. Tabs on convex edges will be inset so that they do not collide with the target surface. Tabs on concave edges are not supported yet.

JSON export

The unfolded net can be exported to JSON for automated processing.

v1.3.1

Released as an extension for Blender 4.4.

Compared to the built-in version of this extension, this release mainly updates code structure for current Blender. However, there are features visible to the user:

• Improved packing algorithm that fits islands to as few pages as possible.
• Fixed all variants of textured export.

Release blender-3.5.0

The version of this script bundled with some blender versions does not work properly.

If you're experiencing problems with textured export, find the bundled file io_export_paper_model.py and overwrite it with this one.
