Hi Avi,
Thank you for the response and info, really appreciate it. I already do what you have shown, I can render out just the people by using Render selected>Viewport selection. You can see that when you did that you lost the drop shadows from the character, you retained the reflection for just the floor because you rendered out the floor. But my question is can you get all drop shadows and reflections from just the character for the scene. So you would just choose an objects and not only would it render the object itself but all reflections, refractions, lighting, shadows. that would make it easier for comping in later. The AOV seem to cover all reflections and refractions, not just for a specific object.
