I would say: just BB's environment sphere as a skydome for the ambient lighting, and a single infinite light for Sun (and shadows and some specular), should do the job.

It mimics what we have outside (single sky, single sun), and what other programs (like Vue) are doing. Poser IDL is not that different.

Extra lights are required for the same reasons as one could use a flash when taking pictures in real life, but that's about it then.

Usually I'm wrong. But to be effective and efficient, I don't need to be correct or accurate.
