I’m try to get an effect of gleaming light reflecting along the edge of a metallic object.
Not dissimilar to the Viacom logo in this video at the 19:12 point.
I’m curious how you guys would do this.
Just move an emitter across something reflective, while it’s either behind or not visible to the camera. Not too hard to do.
If rendered in Cycles you can turn off the emitter’s visibility to the camera in the Cycles Settings of the object’s properties panel.
