Howdy, y'all!

A while back, I asked y'all for some help
in making a "glow" in a rendered image
("http://www.lugnet.com/cad/ray/?n=127&t=f&v=a").

I took your suggestions and implemented them
as best I could, and I've posted the results here:

"http://www.brickshelf.com/gallery/fwcain/povray/lich5e.jpg"
"http://www.brickshelf.com/gallery/fwcain/povray/lich5e.pov.txt"

I'm still not quite satisfied with the results.
I'd like to have more of a brighter, "mote"/"pinpoint"-like glow
within the "gem" (atop the staff"),
and I'd like for about half (40-50%)
of the actual light coming from the "gem",
with the remainder coming from the "ring of fire".

Any suggestions/advice will be cheerfully accepted!  :-)

Thanks,
Franklin

(...) A couple of things to try?--(dunno if these will work)-- - Put a point light source inside the 1x1 cylinder brick atop the staff and crank its luminosity up to (10,10,10). Then tweak that gradually downward since it'll probably be too bright. (...) (25 years ago, 23-Mar-00, to lugnet.cad.ray)

Two things, First, I noticed that your ambient value for the glow color was 2.0. This promots to a color vector of <2.0,2.0,2.0> The largest legal color vector is <1.0,1.0,1.0>. I suggest you drop the ambient value to 1.0. Second, I noticed that you (...) (25 years ago, 23-Mar-00, to lugnet.cad.ray)

(...) Hello, 1. To make a light stronger you can use a multiplier. For example: color rgb 2*<1,1,1> (double the light of the light source) or color rgb 0.5*<1,1,1> (half the light of the light source) or any other multiplier you like. 2. You can use (...)
