A script/mod for converting .obj files to minetest nodeboxes
Run the python script convert.py with the argument being the path to your .obj file. An optional second argument is a float scalar for the output, since often minetest treats the scale of models differently from nodes.
convert.py <filename> [<scalar>]
For example, run convert.py models/sample.obj 0.5
This will output into the terminal a lua table which can be copied into a mod for use as a nodebox.
