A real-time rendering system accessible in the free and open-source 3D modelling program "Blender". The rendering system uses similar methods to video game rendering systems in favour to the more good looking, but less performant path-tracing system, which is called "cycles" in Blender. Eevee is used to get an idea of what your final rendered product will look like during the editing stages.
I made this coffee cup in Blender, and rendered it through Eevee
