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 2 .mu files.
• it may still break, back up your work.
