No, it's just that recently I've noticed my postings seeming to be
incredibly caustic and inflammatory, and I'm not doing it deliberately.
maybe I'm just having one of those months <sigh>

You can create a sphere at <0,0,0> and a point light source at <0,0,0>
and as long as you set the sphere to no_shadow, the light source will
apply to the rest of the scene as if the sphere wasn't there.
As far as I understand it, this is all that POV does internally when you
specify a looks_like. (Although it creates a group containing the light
and sphere, which is easy enough to do in Moray :)
In other words, all looks_like does is put a visible, completely
transparent (can you say oxymoron? :) object around the light source.
The light source still acts as a point/spot/area light, regardless of how
big the looks_like object is.
Did that make any sense? And if not, would somebody else like to try
explaining it?
Bye for now,
Jamie.
