Another couple renderings of the Alabama Welcome Center building, one
showing it late in the day. I've about got it put together right, less some
minor details, so this is basically how the place actually looks. Unlike my
previous renders of it, which weren't very accurate, this now has the upper
front (or facade) as it should be.

I came across some trouble with reflection exponent causing blacked out
areas. At least, that's what I'm thinking must be part of the problem.
Radiosity exaggerates the problem to the point of obliterating most of the
building entrance area. Perhaps something I'm not doing right, just not sure
yet. Anyone reading this seen such a thing happen themselves? I'm guessing
adc_bailout or max_trace_level, or both, could be the solution/problem.

The blank, or black, artifacting is so severe with the introduction of, e.g.
'exponent 0.8', into the reflection statements that I thought it unusual,
having not noticed anything this bad before.
