Is there a checklist of things to check when an object won't show in renders or 3D view?
I have one spotlight parented to an object that moves during animation. The spotlight has a node setup to shine a special emission pattern, but I don't think that's relevant. I'm using Cycles. It worked great the last couple weeks, but about an hour ago the lamp's output no longer shows in renders and I don't see it in the 3D view.
What could I have klutzed up this time? 'N' shows the transorm to be reasonable. I didn't accidentally move it to inside its parent object, or some other object. I didn't hide it with 'H'. I haven't touched this spotlight for any reason since last week.
