How do you make a light cone like in this pic:

    Not sure which render engine you're using, but could u load a cone primitive or better yet a cylinder primitive either from Studio or your favorite modeling program, scaling either end to your specs. Texture the cone or cylinder with a cloud or grit texture and make the whole thing Emissive? Maybe play with cutout opacity/transparencies a bit in conjunction. This obviously would be easy if one was using volumetrics and a spot-light as you know, but there are no volumetrics in the scene that I can see from my phone screen. Maybe some long-timers would know, heck I'd like to know too, more so when you don't want to use volumetrics to pull of such an effect, but yet still have a beam.

    I suspect both the light and the sparks are 2D postwork.

    In 3DL, you could use Atmospheric camera and set only the light from the front to be flagged to create the light cone.

    In Iray you could use a fog volume and do two passes, first with all lights on and fog off, second with only torso light and fog on, and then layer/combine them.

    But... most likely it's done in post, which is the easiest approach.

    There ya go, postwork. Certainly. I'm wayyyyyyy to stuck in model mode.

    I keep trying to do fog and rays in render and keep regretting not just doing it in post. ;)

    Since we're in The Commons, and no software has been specified, I might mention that Carrara Pro has this effect built-in.
