Because your reflector is specular (shiny) this is a caustics path-- I don't recommend trying to simulate this with caustics and path tracing, though-- it will probably take too long. If you make the reflector surface less shiny and more matte you'll get some more reflection-- indirect lighting must be on if you're not using the path tracer.

So far so good. Things I found out with lights and X-Refing<br />
1. Lights fittings as blocks in origin drawing do not get recognize in Nxt.<br />
2. Lights like RPC are better insert in the final scene.<br />
3. Lights from previous versions AR3/4 do not work well in NXT.<br />
<br />
<br />
In the scene attached, the parking lights are diffuse lights directed upwards but are expected to be reflected downwards by the reflector, this is not working why?<p style="text-align: left;"><img alt="" src="http://storage.ning.com/topology/rest/1.0/file/get/55255847?profile=RESIZE_1024x1024" width="721"></img></p>

I doubt you will unless theres something illuminating. There are no lights on in the house. No Street lights glowing. No landscape lighting.<br />
<br />
I live out in the middle of nowhere and this is exactly what it looks like this time of night.

The windows as light sources is because the model was originally an exterior one so the internal partitions are missing. So it is a cheat way out.<br />
Done all you advised including setting the brightness in the tone generator to -0.8(<a href="http://nxt.accurender.com/forums/t/4159.aspx" target="_blank">http://nxt.accurender.com/forums/t/4159.aspx</a>)<br />
