Usage:
In vox-to-schematic.py change INPUT_FILE and OUTPUT FILE to your desired locations
Then run python vox-to-schematic.py
During runtime, you will be asked to supply a block to correspond with each color, the format there is the minecraft id of the block (e.g. 'iron_block')
If you want to run multiple iterations and keep your colors, at the end of the program values in {} will be printed, you can paste those into the colors variable
The code works using my fork of py-vox-io. install it via pip install -r requirements.txt
