Some Lighting Effects in Games

some lighting effects i like, sometimes surprisingly hard to find much about how to make them. especially without downloading (and often paying for) a bunch of new tools.
* lots of stuff with glass-like materials:
** transparent material illuminated from behind (not sure what the word is for this, if there is one). not necessarily "subsurface scattering", which is often for materials you really can't see through. not like "blurry glass" that blurs what you see on the other side, but fails to itself be illuminated by light striking its surfaces. more like glass with a thin film of dust on it, but you can still see clearly through the glass. or clear plastic. can just be surface illumination. but currently what i've got in Unity, this only appears from one side, not if it is lit from behind, and only illuminates the first surface the light touches, not the surface on the other side where the light exits.
* local volumetric fog/smoke.
** realistic lasers
