RSS Open Rails WAG Builder (Clean Baseline)

Why this tool?

Writing WAG files from scratch can be a hurdle for people who don't do it very often. There are some good online references, such as https://www.coalstonewcastle.com.au/physics/wag-settings/ but this can also lead to information overload.

This script will help get you started creating a WAG file for standard rolling stock that can build OpenRails style files that rely on Includes and multiple freight_anim() definitions.

This tool is designed for creators who generate content with Blender and wish to move from the EXPORT step to OpenRails-Ready content with minimal effort.

Key Design:

• YAML defines wagons
• sound_profile controls sound include
• assets folder is authoritative source of Shapes and textures
• Variants share one folder
• Copies textures referenced by .S files
• No recursive dependency scanning (Up to content creator to resolve)
• will process ALL YAML files in the wagons folder

NOTE: You should move all processed YAML files to a backup folder.

Install:

Python 3.x
pip install pyyaml jinja2

Run:

python wag_builder.py
python wag_builder.py <TRAINSET_PATH>
