POV-Ray: Transparency using fade_color

[Roland Melkert]

What I think is missing is some 'milkyness' in the transparent parts, some scattering of light inside them to make them glow. This is especially apparent for transparent parts in front of a dark background.  Using a scattering media might be a solution, but that only works on hollow objects.

This is what my current settings give.
   

Code:

#local ldrawPlasticNor=normal {
bumps 0.001
scale 0.5
turbulence 0
};

#local ldrawPlasticFin=finish {
diffuse 1
brilliance 1
conserve_energy

specular albedo 0.1
roughness 0.01

reflection 0.15
};

#local ldrawPlasticTrans_f=0.75;
#local ldrawPlasticTrans_t=0.25;

#local ldrawPlasticTransInt=interior {
ior 3
fade_power 2
fade_distance 10
};

The hardest part is found tweaking is getting transparency good for all colors as especially red and yellow seem to loose their transparency very fast.
