From Rigs of Rods Wiki
Welcome to the Rigs of Rods Wiki!
The goal of this Wiki is to document files format used by Rigs Of Rods, to allow content creators to modify and create content for the game. It hosts also the FAQ.
First, a word of caution: Rigs of Rods is still under development, and file formats may change at any moment, as well as semantics and physics behavior, so your creation may not work on the next versions of Rigs of Rods. You have been warned. However, I don't expect to do major format modification now, and incompatibilities that may arise should be easy to fix from version to version.
