Fade.Studio has been fooling around with different materials in Cinema 4D. It has been a while since we used Cinema 4D so all is a bit rusty but we are getting there. For the studio we used the light kit pro by Greyscalegorilla adjusted with blue and purple lights from the sides. The material for the balls exists of luminous orange flames and dark blue greyish surrounding. The luminous orange with the dark studio gives a nice atmosphere to the whole set.
A sphere is a perfectly round geometrical object in three-dimensional space that is the surface of a completely round ball.
