Podium Walker has an option in the Light Panel that allows you to use Sky Color for Ambient Light.

The indirect light created by ambient occlusion will read the sky color and use the sky color as the color for ambient light. For night and early morning scenes, where the exterior natural light is predomninantly the sky light, having this option on will produce realistic rendering even for interior animations.

With this new version, an option to match ambient light with the exterior the sky color has been introduced. This new feature can make night scenes look much more realistic than previous versions. See the difference below.
