Rigs of Rods, by default, includes only a small selection of built-in content. Most vehicles, terrains, and other additions are provided as user-generated mods available through the official Rigs of Rods repository. These community-created assets are separate from the core project and are not covered under the project's license, as they are contributed and licensed by their individual creators. As such, they will never be included with the game by default.

As of version 2022.04, resources can be installed from within the game itself. Read the Guide to Installing Mods.

Creating mods for Rigs of Rods can be a challenging yet highly rewarding experience.
