Is it possible to soften the edges of the light projected on a surface? ie: If I place a symbol using the inst insertion tool, and then tik the "Light On" box in the info pallet, the symbol will now project it's light to wherever I place a focus point, but all of these have a hard edge. A Studio Beam or a Colorblast, for example, is a soft edge light, yet the projected light in renderings is hard. Can I change/fix this?
