1.0.2 - Bug Fixes

A long-overdue update to fix support with newer Blender versions.

Bug Fixes

• Fix support in newer Blender versions, up to 4.0.
• Run tests using Python 3.10.

1.0.1 - Bug Fixes

A small update to fix a single bug.

Bug Fixes

• Fix the resource ID of exported materials to be integer.

1.0.0 - Big Bang

For the first stable release, the full core 3MF specification is implemented.

Features

• Support for importing materials, and applying them to triangles of your meshes.
• Support for exporting materials from Blender with a diffuse color.
• Metadata is now retained when editing existing 3MF files.
• Relationships are retained when editing existing 3MF files.
• Content types are retained when editing existing 3MF files.
• Added support for the model types "solidsupport", "support" and "surface".
• Support and solidsupport meshes are hidden from any renders.
• 3MF part numbers are retained when editing existing 3MF files.
• Files marked as MustPreserve are retained when editing existing 3MF files.
• PrintTickets are retained when editing existing 3MF files.
• When metadata, relationships and content types clash when loading multiple 3MF files into one scene, the most common denominator is kept.
• Metadata, relationships, content types and part numbers are retained when the scene is shared through a .blend file.
• The object names are now stored in the 3MF files as metadata.
• Content types are now being read out, allowing for any file type to be anywhere in the archive.
• Automated tests improve stability of the add-on.
• Actions are being logged in Blender's log stream.
• If anything goes wrong, errors and warnings are being logged in Blender's log stream.
• The code is now compliant to Blender's code style requirements.
• Added support for new "Adaptive" units in Blender.
• Transformation matrices are written more compactly.
• Vertex coordinates are written more compactly.
• Warn the user if the 3MF document requires 3MF extensions that are not present.
• When exporting, you can now configure the number of decimals to write.
• Material colors are rendered in Blender with a BSDF node, and converted back to sRGB when exporting.
• The exported 3MF archive is now compressed with the Deflate algorithm.
• Allow installation via .zip file.

Bug Fixes

• No longer crash if faces are provided with negative vertex indices.
• Importing multiple 3MF files in succession no longer allows resource objects of old files to be used by new files.
• Exporting multiple 3MF files in succession resets the resource ID counter every time.
• No longer crash if there are no access rights to files to read or write.
• Fix writing of transformations for resource objects that have components.
• Fix writing transformations if multiple transformed objects are written.
• Resource objects that have components can no longer have mesh data of their own.
• No longer create meshes when an object has no vertices or faces.
• Transformation matrices and vertex coordinates will no longer use scientific notation for big or tiny numbers.

0.2.0 - Get Out

This is another pre-release where the goal is to implement exporting 3MF files from Blender.

Features

• A menu item is added to the export menu to export 3D Manufactoring Format files.
• Saving Open Document formatted archives.
• Support for exporting object resources.
• Support for exporting vertices.
• Support for exporting triangles.
• Support for exporting components.
• Support for exporting build items.
• Support for exporting transformations.
• Support for conversion from Blender's units to millimetres.
• You can now scale the models when importing and exporting.

Bug Fixes

• The unit is now applied after the 3MF file's own transformations, so that models end up in the correct position.

0.1.0 - Come On In

This is a minimum viable product release where the goal is to reliably import at least the geometry of a 3MF file into Blender.

Features

• A menu item is added to the import menu to import 3D Manufactoring Format files.
• Opening 3MF archives.
• Support for importing object resources.
• Support for importing vertices.
• Support for importing triangles.
• Support for importing components.
• Support for importing build items.
• Support for transformations on build items and components.
• Transforming the 3MF file units correctly to Blender's units.
