I cannot get even the most simple dispersion scene to work in Mega 0.7.
I BTW STFM!

Can someone post the most simple scene for dispersion in 0.7, with a
light source hitting something and we see different colors afterwards?

Can someone also tell me exactly what POVRAY.INI settings, what global

but I get no dispersion, on my "other PC".

You know that you need the spectrum macro for your lights?

dispersion and disp_elems must be in the interior {} as i know... look in
the MegaPOV demo files! prism.pov or threelens.pov

Dispersion, per se, doesn't make you get a spectrum with photons. Most times
it just makes the refracted rays look yellowish. If you want to get a
spectrum you should specify a color_map inside a light_source block. This is
just what the spectrum macro included in the prism demo scene does. As I
said before, sometimes the spectrum seems to disappear. Just rerender it and
you should finally get it. No specific ini or global settings are needed
(but I may be wrong...).
