Analyze a scene for the "heaviest" elements?

Hi guys,

Is it possible to analyze a scene to find the "heaviest" objects that make it render too slowly? I'm rendering one now, and, at first glance, it doesn't have anything too special. One G8F character, some water, some house elements, some background, an HDRI... The usual stuff. But it's being rendered way slower than I'm used to with the current PC. So, is there a way to know what's making it that slow?

    Scene Analyzer Organizer Simplifier and Scene Optimizer (the latter is faster...) can both give you an analysis by showing the info. of polycounts, texture maps / size used, SubD-Level, distances, etc. so as to help you find the "heaviest" objects from different perspective.

    However, there're also some factors rather than assets that can bring you slow rendering, e.g. bad lighting setup, inproper rendering settings, renderer fallback to CPU, etc. So you need to dbl-check them at the same time.

    Hm. Lighting can be it, come to think of it. Is there a simple guide to proper lighting? 'Cause I just thought that maybe a single point light stretched to cover the whole floor isn't exactly the best solution. Or is it?

    And thanks a lot for the Scene Optimizer(s) recommendation; they sound like useful tools.

    Well, that'll depend on your scene setup as well as what lighting effects you want to get. The better and faster lighting pattern that can give you rapid rendering is to use an HDRI as the ambient light, plus 1 ~ 3 spotlights to light the partial areas on the character(s), e.g. eyes catch light, rim light, etc. 

    In that way, in most of the cases, you can get a render with pretty good quality within a short time.
