Blender is the free and open-source 3D creation suite. It supports the entirety of the 3D pipeline—modeling, rigging, animation, simulation, rendering, compositing and motion tracking, video editing, and 2D animation pipeline.

Unity is a cross-platform game engine developed by Unity Technologies. The engine can be used to create three-dimensional, two-dimensional, virtual reality, and augmented reality games and simulations, and other experiences. Industries have adopted the engine outside video gaming, such as film, automotive, architecture, engineering, and construction. Unity is free for personal scratch use.
