These images were amazing in their clarity and perfect in reflecting and refracting light through the scene. Raytracing isn't new in Max, but making sense of all the raytracing features can be confusing.

Raytracing in Max can be used with the Default Scanline Renderer using the traditional Raytracing materials and controls, or it can be enabled at the renderer level using the mental ray settings.

This engine takes the rendering in Max to a new level, enabling you to render your scenes with amazing accuracy, but mental ray doesn't only enable raytracing. It also includes a host of advanced rendering features including caustics and global illumination that are physically realistic.

Using Raytrace Materials

Raytracing is a rendering method that calculates image colors by following imaginary light rays as they move through a scene. These rays can travel through transparent objects and reflect realistically off shiny materials. The results are stunning realistic images, but the drawback is the amount of time it takes to ...
