OpenMW OpenSceneGraph exporter for Blender

OpenMW OpenSceneGraph exporter for Blender, making the format viable for importing meshes into OpenMW using a libre format.

This is a fork of the Blender OpenSceneGraph Exporter updated for 2.80+ Blender versions and adjusted to support the specifics of Blender to OpenMW asset pipeline.

Installation (Blender 2.8+)

  1. Copy the osg directory to the location where Blender stores the scripts/addons folder on your system (you should see other io_scene_* folders there from other addons). Copy the entire dir and not just its contents.
  2. Go to the Blender settings and enable the "OpenMW Native" addon.

Command line usage

osgexport needs to inject the path to exporter modules into PYTHONPATH. The injection is done by reading the value of the BlenderExporter environment variable (see __init__.py).

$ BlenderExporter="/path-to-osgexport/blender-2.5/exporter" \
    blender -b "input.blend" \
    -P "${BlenderExporter}/osg/__init__.py" \
    -- --output="output.osgt" \
    [--apply-modifiers] [--enable-animation] [--json-materials] [--enable-animation] \
    [--bake-all] [--bake-quaternions]

Tests

To run tests:

mkdir tests && cd tests
cmake ../ -DBLENDER:FILEPATH="/my/path/to/blender" -DTEST=ON
make  # runs test building osgt files for models in blender-2.xx/data/
make test  # runs python test located in blender-2.xx/test/

To troubleshoot python tests: ctest --debug or ctest --output-on-failure
