## Installing
1. Copy the [io_ogre](io_ogre) folder into the [$BLENDER_DIR](https://docs.blender.org/manual/en/latest/advanced/blender_directory_layout.html)`/scripts/addons` folder.
2. Enable the addon in Blender: `Edit menu > Preferences > Add-ons`. Search for `'ogre'` and click the box up the top left.
3. Configure the plugin before the first run.
- Set the correct path to `OGRETOOLS_XML_CONVERTER`
- for Ogre (v1): path should point to `OgreXMLConverter.exe`. This can be found in the [Ogre SDK](https://www.ogre3d.org/download/sdk/sdk-ogre)
- for OgreNext (v2): path should point to `OgreMeshTool.exe`. This can be found in the [OgreNext SDK](https://www.ogre3d.org/download/sdk/sdk-ogre-next)
- *OPTIONAL* Set `MESH_PREVIEWER` to a path pointed to `ogre-meshviewer.bat`. This can be found in [OGRECave/ogre-meshviewer](https://github.com/OGRECave/ogre-meshviewer/releases)
- Make sure that `USER_MATERIALS` isn't set to a directory like "C:\\\". The addon scans this path recursively and will crash when it hits a path it doesn't have permissions for.

- Importing of Poses
- Importing of Skeletons works for the most part, but Ogre skeletons conventions are not like Blenders (see: [How to get bone's vector and bone's length?](https://forums.ogre3d.org/viewtopic.php?t=49689))
- Importing of Animations work, but depends on the skeleton which sometimes doesn't get correctly imported
- As of Blender 4.1+, it is now possible to drag and drop files of types: `.xml`, `.mesh` or `.scene` and import them automatically. (https://docs.blender.org/api/4.1/bpy.types.FileHandler.html)

> **NOTE:** Orientation of the imported mesh is assumed to be `xz-y` (Ogre default), the `blender2ogre` Axis Swapping option does not work for the importing process.
