my lights are missing and i cannot figure out why. no duplication data is turned on, layer is visible, no modifications to render passes, all ray visibility settings are left to default.
maybe my setup has something to do with it. i subdivided my top mesh, used the boolean modifier to cut through it, within a small part of it. for the boolean, i used “fake” geometry - a solid cylinder with the diameter of the lights. Under ray visibility, i unchecked all options for the cylinders, and then i placed them on a separate, hidden layer.
