I was just curious before i tried this. I know when you set a light source it's a sphere based projection. I was curious, say if i make a flouresant light bulb, a long rectangular shape, if i made the model emit light, would the light be in the shape of the model? Also, is the current fog, light sensitive. For example, say i have a grate with fog on either side pasing through it. If i had a light source on one side would it make a light beam like volumetric effects? Or would there be anyway to script this.
