Installing

1. Manually copy jbeam_flow directory into Blender's addons directory. Check Blender docs for directory layout.
2. Get antlr4-python3-runtime 4.7.2. Extract src/antlr4 directory into Blender's modules directory.
3. Generate jbeam file parser in jbeam_flow/jbeam/ext_json/
   • Install ANTLR 4.7.2 toolkit.
   • cd into the ext_json directory and generate the parser:

     antlr4 -Dlanguage=Python3 -visitor -no-listener ExtJSON.g4

Usage

Enable the add-on in Blender. Invoke Import JBeam (.jbeam) or JBeam vehicle command to import existing assets.

Todo: expand/more docs
