Hello there,

Being a night scene there was no need to use the mr daylight system object.

In this particular instance only one skylight object was used, with the environment‘s map loaded onto the sky’s color map slot, to have the accurate environment colour in the scene.

Inside the building, about 300 boxes were created( not visible to the camera, not casting shadows and not visible to reflections), to emulate a light source we simply applied a basic pearl finish material to them. Next, we loaded the environment’s map materials to their colour and upped the RGB values; the colour material was then copied and instanced onto the additional color/self illum slot. To achieve different colour variations for each box, different cropping/placement areas of the photograph were picked

The image came straight from 3Ds Max and Mental Ray.

Any comments are welcome
