increasing density of beam light in volume rendering I am simulating in animation a film projector with a light beam in volumetric.  On the pic attached you can see that the beam is quite light.. I want to densify the beam more like an intense light coming from the lens..  I attach the blend file http://pasteall.org/blend/index.php?id=45259 and a pic showing my current state..
I have tried to balance volume scatter and  absorption but with no satisfactory result.. Can you suggest something 
Thanks
When you are using scattering you need increase the intensity of the light.
