#!BPY """ Name: 'OGRE for Kenshi (*.MESH)' Blender: 2.80 Group: 'Import/Export' Tooltip: 'Import/Export Kenhi OGRE mesh files' Author: Someone Based on the Torchlight Impost/Export script by 'Dusho' Thanks goes to 'goatman' for his port of Ogre export script from 2.49b to 2.5x, and 'CCCenturion' for trying to refactor the code to be nicer (to be included) """ __author__ = "someone" __version__ = "0.9.1 13-Sep-2019" __bpydoc__ = """\ This script imports/exports Kenshi Ogre models into/from Blender.
