“fryrender is the unbiased spectral renderer developed by Feversoft. All the elements involved in the render (materials, lights, cameras, …) are based on physically accurate models up to the0 point that when you hit render a simulation of the real behavior of light happens inside. Moreover, fryrender is the first engine of its kind capable of transforming scenes into a format that can be navigated in real-time with the aid of our Virtual Reality technology Random Control 4. Using Cinema4D and Fryrender Andreas will explain you the concept of rendering in Fryrender”
