I use 3DS Max v7--can't afford to upgrade
. v7 is fine for everything I currently need.... I rendered out the entire building/land and dropped in a sky and adjusted the sky tint/colors to the lighting of the building, and boom, done!
Once it's 'laid into' the 3D City, it'll have a rendered sky with trees, more light sources--haven't added the light poles for the pool, nor the pool underwater lights--which will be new for me.. never added a light source under water before.. gotta use a refraction setting with falloff... with a bit of glow... that's a pain.
