Is this possible? No matter what length/width I use on a light it always ends up as a square at the end of the directional volumetrics.

Vray light. Anyway to change size proportion when using high directional values to create laser type lights?

Hi there. That makes total sense but if you try to have a thin laser type light from a small source...ie, a length of 2cm and width of 0.5cm for example and then change the directional to something like 0.8 the light will not stay thin in proportion. It will expand out and not remain flat...like a laser light...
If you imagine the below light starts from a very small point and only expands in length but not in height. Is this possible?

HI, the laser emits parallel light beams. This means a directional value of 1. Anything other than 1 is not a laser but a regular projector.

What do you mean by change aspect ratio? Can you not just change the radius of a Disc VRayLight (directional 1.0) ? Or the length and width of a Plane VRayLight (also directional 1.0) ?
Or does that not do what you need?
Basically, with Directional set to 1.0 the VRayLight produces a straight beam, like a light saber (with no taper) or laser.
For laser, though I have sometimes found a simple self illuminated cylinder to do the trick, but it depends on the shot.
