If I'm perfectly honest, I can't remember now the exact use case, it could
be
that we've already found a suitable work-around or alternative way of
dealing
with it. I only remember at one point thinking it would be useful.

I presume you're talking about a new type of datablock for the preview
settings,
and this is not something currently available?

The problem we have with the built in scene is that it relies on material
alpha/transparency and other non-physical properties to light it.
The scene+camera is enclosed in a sealed box and all the lights are outside!

I think it would be best for LuxRender if we just construct our own scene,
trying to translate the existing one is probably more trouble than it's
worth.
