MaxQ is distributed the Unreal Engine Marketplace as a free Plugin. To obtain MaxQ simply download it from the Marketplace and enable it in your project.

The Plugin will locally install to a directory within Unreal Engine, such as:

C:\Program Files\Epic Games\UE_5.0\Engine\Plugins\Marketplace

You’re now ready to begin using the MaxQ Toolkit and leverage NAIF’s SPICE tools from Blueprints.

Rebuilding for distribution as a Plugin

Full Source code to build the plugin is available on GitHub:
MaxQ Plugin Source Github Page

This is rarely needed, unless you’d like to rebuild the plugin yourself. But it’s good to know it’s available if needed.
