Per ren_mem's request: "Hey LCBoliou, got an example from vue or truespace of the volumetric light effect? Are you using the default renderer in TS or the nicer plugin.Thanks." Here is a trueSpace 6.6 render with the raytraced light cone. I didn't turn all the material/light features on, in order to emphasize the obvious. My wish is for Eovia to give Carrara the same ability. I placed vertical slats in a green colored transparent material, to simulate a green colored glass. Note how the beams go through the material, are attenuated, and pick up the material color.
