No CD can do without it
Have you ever tried to render, let alone animate a CD-ROM? Using standard 3ds Max tools and materials makes it nearly impossible.
Adjusting the spectral rainbow colors correctly is just a huge task. Arranging the colorful streaks and always pointing to the center of the CD are also very tedious.
The fR-CD shader material manages the interaction of light rays that hit the surface based on true optical effects.
A freely adjustable spectral color gradient defines the angle at which a color should be reflected. As the camera moves, the CD-ROM effect changes accordingly.
