Stupid Question

I have searched and searched to no avail. Even through the book.

Is there a way to hide an object from the camera other than turning down the Alpha?


Maybe… put it on another layer and hide that layer.

What is the goal? To hid the object but cast shadows? Hide the object from the camera but use as a parent? Otherwise, 0 alpha and moving to another layer is the way to do it.

Actually to have say a plane as a light emitter, but when you render it will not show up. Like say lightwave for instance, you can turn an object off to the camera for Render.
