SubwaySim Wiki

This section covers everything related to vehicle creation and implementation in SubwaySim 2. Here you will learn the complete workflow required to create a functional vehicle — from 3D modeling and rigging to Unreal Engine setup and Lua integration.

The focus of this section is on practical implementation. Blueprints and Lua scripts are explained directly within the corresponding creation steps.

The following chapters will guide you step by step through the vehicle development process:

• Fundamentals

Learn the core requirements for vehicle development, including scale, coordinate systems, naming conventions, and general best practices.

• Creating a Vehicle in Blender (Rigging)

Understand how to model and rig a vehicle in Blender, including bone hierarchy, pivot setup, and animation preparation.

• Importing the .FBX File

Learn how to correctly import your vehicle mesh into Unreal Engine and configure import settings for optimal results.

• Creating Physics Assets

Set up collision bodies and physics constraints required for correct interaction and simulation behavior.

• Creating a Control Rig

Create a Control Rig to control and animate vehicle components.

• Creating Animation Blueprints

Define animation logic, state machines, and parameter-driven animations for vehicle movement and systems.

• Creating a Vehicle Blueprint

Assemble all components into a functional vehicle Blueprint.

• Creating a Vehicle.lua File

Integrate the vehicle into SubwaySim 2 using Lua scripting.

Together, these chapters guide you from the first 3D model to a fully functional vehicle inside SubwaySim 2.
