Hi,
Blender 5 no longer includes COLLADA support, so I recently published a new Blender add-on that brings COLLADA import and export back to Blender 5+.
AssetKit-Blender repository (Blender Extension/Add-on):
It supports COLLADA 1.4, 1.5, and 1.5.1+, with both import and export functionality.
The add-on uses my native AssetKit library under the hood. AssetKit itself is only around 1.2 MB and is designed to be fast and lightweight. You can also find benchmarks in the above repo’s README comparing it with Blender’s previous COLLADA implementation.
Exported XML(dae)/json(gltf) is not pretty-printed by default, mainly to improve performance and reduce file size. You can format it later with xmllint or a similar tool when needed.
You can download the latest release here:
https://github.com/recp/assetkit-blender/releases/latest
Please follow the installation instructions in the README.
AssetKit repository:
AssetKit supports fast import and export/convert for COLLADA, glTF, and other formats. It also includes a CLI which allows to convert between formats in cli:
assetkit --c <input> <output> [options]
Run assetkit --help to see the available options.
AssetKit can also serve as a high-performance, reliable converter between COLLADA and glTF ( including others formats too), available as both a library and a CLI…
Feedback, bug reports, and test files are welcome
