In POV-Ray 3.6.* and earlier the ambient keyword was often used to
effect a glowing finish. This usage has been deprecated since POV-Ray
3.7, and 3.8 warns you if it thinks that you are doing that.
If POV-Ray 3.8 guessed correctly, and you want a glowing object, then
replace 'ambient' with 'emission'.
If you really do want ambient 0.3, then add 'emission 0' to that same
finish statement. This will suppress the warning.
Ambient 0.3 does seem rather high to me, but it's not for me or POV-Ray
to tell you, as an artist, not to use it that high. The 'emission 0'
tells POV-Ray 3.8 that you have consciously made that choice.
