Unity3D is a free (for non-commercial use) game development tool, available on the Windows 64-bit platform (Windows 7 through 10) and the Mac (OS X 10.9+). This software provides developers with tools to model terrains and develop digital environments that can be exported to a great variety of platforms.
Unity3D comes with an asset store from which models and extensions can be downloaded and added to the platform. Alternatively, models can be easily added and imported from third-party software development suites.
