mental ray Renderer
mental ray is a popular general-purpose renderer that has fantastic capabilities. One of mental ray’s strengths is its ability to generate physically accurate lighting simulations based on indirect lighting principles. Indirect lighting is when light bounces from one object in a scene onto another object. In addition, incandescence or self-illumination from one object can light other objects in the scene. A direct light, such as from an omni light, is not necessarily required. Another thing to consider is that mental ray’s reflections and refractions take on very real qualities when set up and lighted well.
