playcanvas2obj

A quick and dirty script that attempts to convert a PlayCanvas JSON model into a (partial) Wavefront OBJ file. See example_input.json for an example of the expected input format.

Current status

This script only knows how to extract the vertices from the input file and print those vertices in OBJ format. More complete translation is not yet a goal.

Usage

Download the playcanvas2obj.py script and run it using Python 3, passing in a URL or local file path pointing to a valid PlayCanvas JSON model.

# URL as input
python3 playcanvas2obj.py https://raw.githubusercontent.com/mccutchen/playcanvas2obj/main/example_input.json

# Local file as input
python3 playcanvas2obj.py example_input.json

By default, output is written to stdout and can be redirected to a file as necessary:

python3 playcanvas2obj.py example_input.json > example_output.obj

Specify the -o/--output argument to write output to a file instead:

python3 playcanvas2obj.py example_input.json -o example_output.obj

Output format

The output will be a list of vertexes in OBJ format:
