Old Hong Kong Building

Many 3D scenes, cities, and environments shoot short on the realism front - not because of a lack of photorealistic rendering. But rather an unrealistic set of detail elements - and by unrealistic - I mean elements that do not represent the real world.

Personally - I find a HUGE benefit in taking a structured approach - detailing by category simulating real-world aspects in a scene namely:
1. the built environment - everything that is man-made and built onto the base structure
2. Electrical components
3. Mechanical components
4. Plumbing and water systems
5. Waste and scatter

Hope this helps someone out there!
