edited to note that I’m on pc and had a colleague ask me if there was a way to adjust this location and this thread was as close to a solution as a I have gotten.
Hi Don - there is no way that I iknow of to change the location of the default light used in rendering. In rendered display mode, however, you do get to play, in case that helps, but it will be static and not camera based. If static is OK, then placing one or more lights in a template file, setting the file to use lights on layers that are off, and putting the lights on their own layer is the way to go.
