Just for fun, why not create a mirrored disco ball? Think of how many scene could benefit from the glitzy, glamorous, magical star-like effect only offers by the 1970s gift from the future, the mirrored disco ball.
With a more serious tone, a sphere bedazzled with mirrors and its effect on the walls is an interesting exercise in 3D, and easy task within Cinema 4D. Matt Umney walks through how you can create your very own disco mirror ball, using caustics to create the realistic lighting projected on to the walls of the scene.
The magic comes from a light source emitting caustics, attributed to both the lights and the render settings, creating those dancing light beams that sparkle around the walls. Great fun.
