Maps plugin for Lumix Engine
You can use this plugin to easily create real-world terrains in Lumix Engine. It downloads height maps from Amazon and satellite maps from EOX. It can read OSM data and use them to place roads, buildings and other objects. Read their licenses to find out what can you use this data for.
You can use itch.io to download the engine with maps plugin already installed. It's used to develop On the hunt game.
