Monster Renderer (tile / region rendering)

EDIT:
i have since updated this script. read about it

here




monster_tile_renderer
monster_tile_renderer_2

usage note:
- filename won't update until you restart blender (Working on it! You can still modify by hand)

installation note:
- place monster_tile_renderer_2.py in your scripts/addons directory
- the addon will appear in the 'render' addons list.

autostitching
for autostitching i wrote a tool, it uses and older version of Python 2.6/7 because PIL image library is used for stitching. Auto_Stitcher Download.py
# GPL2 license - code by Dealga McArdle (zeffii) 2011 july 12
'''
usage, 
1) stick the output of Monster Tile Renderer in a folder.
2) set the path variable to that folder  ('..fullpath/stitching/files/')
3) run the script.
