I’m hoping I could ask for some help regarding lighting. I’m currently working on a project that will involve light and volumetric shadowing. Ideally the work in progress project involves creating a beam of light hitting object as a result creating volumetric shadowing…for now I’m just working on still images and eventually will do some animation.
Normally you can add a lamp (Spot light), turn the Halo option on in the shadow and spot section and increase the number of Halo Steps and viola…you get volumetric showing produced by the object.
My questiois this…is there a way I can control the shape of the light…by this I mean I dont want a cone effect in essence a spot light… what I want is to produce a beam of light that will be pointed toward the object and then produce the volumetric shadowing.
Any help would be greatful.
PS. To clarify the above I have attached an image to what I would like to achieve.
