Lights with volume

After expermenting with lights last week we have now learned who to create lights with volumemetrix (showing the volume of light), this creates an actual beam of light rather than just the spot (when using target spotlights).  To create other effects  such as an erire corridor .
We also learnt how to filp one sided polygons to create an Inverted box, I can picture this being useful when I am Creating our final animation as it can be used to create the inside of buildings or corridors. If applied to the box modeling techniques and textures we could now create  a full atmospheric scene such as a run down caslte, using blue dim lights to create a cold feel, textures to add depth and feeling to the walls and with box modling there is no limit to how we make the castle look.
