Sorry, no info on this.

This is how I do it in my Christmas renderings,

#declare Color46_t = #if (version >= 3.1) material { #end texture {
pigment { rgbf <1,0.905882,0.211765,0.90> #if (QUAL > 1) filter 0.85 #end }
finish { ambient 0.6 diffuse 0 }
#if (QUAL > 1)
finish { phong 0.5 phong_size 40 reflection 0.9 }
#if (version >= 3.1) #else finish { refraction 1 ior 1.25 } #end
#if (BUMPS) normal { BUMPNORMAL } #end
#end
} #if (version >= 3.1) #if (QUAL > 1) interior { ior 1.25 } #end } #end
#declare light_point = light_source {

color rgb 0.4*<1,0.905882,0.211765>
fade_distance 100.0

{Color46_t} }
}

The important thing here is that I do not put a light inside a brick, but
declare a light which 'looks_like' the brick, and putting this in the model
instead of the original brick. I'm also using a special color, to be able to
experiment with the different parameters.
The fourth value for an 'rgbf' is the transparency. The reflection values
might also need some twiddling.
With a lot of extra lights, the overall lighting needs adjustment too (and AMB
etc.). All in all, it's a lot of test renderings, changing !JUST ONE!
parameter at a time between renderings...

| (...) Thanks! :-, But I had trouble positioning the light_source; it wouldn't be rotated and translated like an object. Did you have to figure out the coordinates all over again?
