blender_mineways.py

# Mineways Blender script, for quickly setting materials for Mineways models imported into Blender
# Version 1.01, 6/22/2014
# Distributed with Mineways, http://mineways.com
# Original script by Nicky, see https://www.youtube.com/watch?v=X41QQqCib3A
# Heavily modified by Wyatt Jameson, see https://www.youtube.com/watch?v=hb906Xzh7dQ
# Added "use_mipmap = False" to avoid edge artifacts for grass blocks, etc.

# How to use:
# To the right of the "Help" menu in the upper left, click on the "keys" icon next to the word
#"Default" and pick "Scripting".

# At the bottom of the gray window you'll see a menu "Text"; click it and select "Open Text
# Block". Go to the directory where "blender_mineways.py" is and select it. You should now
# see some text in the gray window.

# To apply this script, click on the "Run Script" button at the bottom right of the text window.

# To see that the script did something, from the upper left select "Window" and "Toggle System
# Console". If you don't have a "Window" menu item between "Render" and "Help", you have an
# older version of Blender and should consider updating. This menu item pops up a console window.
# It isn't critical to see this window, but gives you a warm and fuzzy feeling that the script has worked.
