I was seeing if I could fake a spot light that produced volumetric shadows in some fashion. (Wrath of God Rays I think they are sometimes called.)
So I threw a one ended cone (emmisive on normal facing down the cone) inside a box and added an opacity ramp running down the length of the cone with just a few irregularities on the ramp for the "wrath rays."
This is of course pretty rough and low end... I did not let it cook long or try and clean up noise...but with some work it could give on the desired effect.
The cone is low poly and smoothing is turned on. Why do you think the leading edge of the cone on the floor shows the poly facet shape? Could it be a scale issue? (Similar to transparency map shadows on leaves that show the square poly shadow they are mapped onto when they are too small.)
Anyway its just a test but if anyone has any ideas on how to make the "wrath rays" look more three dimensional and "solid" I would love to hear.
