There are 2 ways to do this -- the quick way and the right way.
The quick way: If it's not a transparent part, and if it's in a well-lit
area, you can crank up the ambient value of the color the part uses.
The right way: You want to replace the POV object of the part, with a
light_source object. e.g. if I wanted my 2x4 brick (3001.DAT, represented
in l3p as the object _3001_dot_dat) to emit light, I put this after the
lighting object is declared but before it's used:
#declare BrickLight = light_source {
<0,0,0>
color rgb <1,1,1>
fade_distance 5
fade_power 1
looks_like { _3001_dot_dat }
}
...then I use the new light_source object instead of the old l3p-generated
object. For example, if l3p gave me:
object { _3001_dot_dat #if (version >= 3.1) material #else texture #end {
Color4 } }
...I would now use:
object { BrickLight #if (version >= 3.1) material #else texture #end {
Color4 } }
For more details, just search for "light_source" in the POV docs.
It's a little weird at first, but once you get the hang of it, it becomes
quite easy.

| Hi, Currently I am working to model the old light bricks (size 2 x 2) Does anyone know if and how it is possible to put a lightsource for POV Ray inside? First renderings of the bricks and the datfiles will be uploaded to my website this evening (...) (22 years ago, 1-Oct-02, to lugnet.cad)
