This doesn't completely solve the problem, since the brick in the
first example doesn't look all that lit up.  But it's something to
keep in mind.


In my 1998 Christmas picture http://web.telia.com/~u16122508/merry.htm (go
to the end of the page) I hand adjusted the lights (one inside each candle)
quite a bit. One important part was the material settings (Color46_t), as
the clear L3P parts are much *too* clear. Most of the light escapes the part
without making it shine. The following is the result of much experimenting,
but not necessarily the 'best' way to do it. Note also the use of
'looks_like' to combine the light with the part it's supposed to light up.

#declare Color46_t = texture {
pigment { rgbf <1,0.905882,0.211765,0.90> }
finish { ambient 0.6 diffuse 0 phong 0.5 phong_size 40 reflection 0.9
refraction 1 ior 1.25 }
}

#declare light_point = light_source {
    <0, -8, 0>
    color rgb 0.5*<1,0.905882,0.211765>
    fade_distance 60.0
    fade_power 1.6
    looks_like {_3062_dot_dat texture { Color46_t } }
}

(...) I notice you're using white as the color for light.dat. Since L3P pays attention to the color of the light, you can use a much darker shade of gray. The following was done with a light inside the trans red brick with a color of 0x02141414 (...) (17 years ago, 25-Mar-07, to lugnet.cad.ray, FTX)
