# A quick and dirty script to convert ModelBase Java code as generated
# by Techne (or possibly Tabula) into Minecraft's JSON model format.
# It is quite limited (it does not handle rotations, as the JSON model format
# is limited in that regard anyway), but it is at least a help.

# Usage:
# modelbase_to_json input.java > output.json

This guide is intended for those with a clear knowledge of general modding and want a quick up to speed on how new things work. If you are confused, please hop on IRC and ask for help!

Blocks and Items

• 1.7: EVERY BLOCK SHAPE EVER was hardcoded into RenderBlocks or your ISBRH. Oh God, just look at that class. Actually don’t, if you value your sanity.
