SilverwingVFX shows how to make a Retroreflector material in Octane Render for traffic cones, signs, and more.

What is a retroreflector? You likely see them all the time, especially with traffic markings. A Retroreflector reflects light to the source with minimum scattering, making a distinct glowing look.

SilverwingfVFX (Raphael Rau) shows how to create a traffic cone material using Octane in Cinema 4D. “it’s something I stumbled upon while doing research for my upcoming Opal Material tutorial. It was unrelated, and I am not 100% sure how it works. But it is reliable and valuable,” Rau says about the process.
