io_object_mu
Blender addon for importing and exporting KSP .mu files.
NOTE: the import/export functionality is still under heavy development, but importing is mostly working for static meshes (minus normals and tangents).
mu.py is the main workhorse: it reads and writes .mu files. It is independent of blender and works with both versions 2 and 3 of python. Some notes on mu.py:
- vectors and quaternions are converted from Unities LHS to Blender's RHS on load and back again when writing.
- vertex tangents are broken (they are incorrectly treated as quaternions), but will be preserved if mu.py is used to copy a .mu file. This is a bug.
- mu.py always writes version 5 .mu files.
- it may still break, back up your work.
